Abstract
The addition of tert-butyl hydroperoxide (tBuOOH) to two structurally related MnII complexes containing N,N-bis(6-methyl-2-pyridylmethyl)ethane-1,2-diamine (6-Me-DPEN) and N,N-bis(6-methyl-2-pyridylmethyl)propane-1,2-diamine (6-Me-DPPN) results in the formation of high-valent bis-oxo complexes, namely di-μ-oxido-bis{[N,N-bis(6-methyl-2-pyridylmethyl)ethane-1,2-diamine]manganese(II)}(Mn—Mn) bis(tetraphenylborate) dihydrate, [Mn(C16H22N4)2O2](C24H20B)2·2H2O or {[MnIV(N4(6-Me-DPEN))]2(μ-O)2}(2BPh4)(2H2O) (1) and di-μ-oxido-bis{[N,N-bis(6-methyl-2-pyridylmethyl)propane-1,3-diamine]manganese(II)}(Mn—Mn) bis(tetraphenylborate) diethyl ether disolvate, [Mn(C17H24N4)2O2](C24H20B)2·2C4H10O or {[MnIV(N4(6-MeDPPN))]2(μ-O)2}(2BPh4)(2Et2O) (2). Complexes 1 and 2 both contain the ‘diamond core’ motif found previously in a number of iron, copper, and manganese high-valent bis-oxo compounds. The flexibility in the propyl linker in the ligand scaffold of 2, as compared to that of the ethyl linker in 1, results in more elongated Mn—N bonds, as one would expect. The Mn—Mn distances and Mn—O bond lengths support an MnIV oxidation state assignment for the Mn ions in both 1 and 2. The angles around the Mn centers are consistent with the local pseudo-octahedral geometry.
Chemical context
A heterometallic cubane cluster, MndangCaMn3O5, referred to as the oxygen-evolving complex (OEC), is involved in photosynthetic catalytic water oxidation (Umena et al., 2011 ▸). The cluster is housed in the enzyme photosystem II (PSII) and consists of high-valent MnIII/IV ions linked by oxo bridges and one dangling MnIV/V ion. Water oxidation is thermodynamically unfavorable, and requires an energy input of 359 kJ mol−1 that is provided by sunlight (Yano & Yachandra, 2014 ▸). Although the exact details of the mechanism for water oxidation are unknown, two water molecules are thought to bind to the cluster to produce one equivalent of dioxygen, four electrons, and four protons (Kok et al., 1970 ▸). Sequential oxidation of the cluster, starting with the CaIIMnIVMn3
IIIO5 core, generates partially oxidized states, Si (where i = number of stored oxidizing equivalents), which store oxidizing equivalents in preparation for O—O bond formation and O2 release (Hatakeyama et al., 2016 ▸; Lohmiller et al., 2017 ▸; Renger, 2011 ▸; Yano & Yachandra, 2014 ▸). Very little is known about the key OEC-catalyzed O—O bond-forming step, because it occurs following the rate-determining step (Retegan et al., 2016 ▸). Proposed mechanisms for O—O bond formation involve either nucleophilic attack by an M—OH group (M = Mn or Ca) at an electrophilic MnV≡O site, or radical coupling between two MnIV oxyl radicals to afford an unobserved peroxo intermediate (Hatakeyama et al., 2016 ▸; Lohmiller et al., 2017 ▸; Renger, 2011 ▸; Yano & Yachandra, 2014 ▸). Developing a wide base of chemical information on a variety of Mn—O species similar to the fragments implicated in the key O—O bond-forming step should aid the development of a detailed understanding of photosynthetic water oxidation. Fundamental concepts obtained from these studies can then be applied towards the maintenance of stable energy reserves and improve the world’s energy economy by storing solar energy in chemical bonds (Lewis, 2016 ▸).
A key step in OEC-catalyzed water oxidation involves the formation of a peroxo O—O bond prior to dioxygen evolution. Previous work by the Kovacs group has facilitated an understanding of the metal-ion properties that favor peroxo O—O bond formation versus cleavage, and O2 binding versus release (Coggins et al., 2012 ▸, 2013a ▸,b ▸,c ▸; Coggins & Kovacs, 2011 ▸; Poon et al., 2019 ▸). Reversible dioxygen binding and release was shown to strongly correlate with metal-ion Lewis acidity. Superoxo, peroxo, and reactive mixed-valent MnIIIMnIV bis-oxo intermediates were shown to form. In addition, thiolate ligands were shown to increase the HAT (hydrogen-atom transfer) reactivity of putative MnIVMnIV dimer intermediates, precluding their isolation (Poon et al., 2019 ▸). In contrast, alkoxide derivatives [MnIII(OMe2N4(6-Me-DPEN))](BPh4) (3) and [MnIII(OMe2N4(6-Me-DPPN))](BPh4)⋯Et2O (4) (Coggins et al., 2020 ▸) react with tBuOOH to form ultimately the high-valent complexes described herein: {[MnIV(N4(6-Me-DPEN))]2(μ-O)2}2+ (1) and {[MnIV(N4(6-Me-DPPN))]2(μ-O)2}2+ (2). The isolation and crystallographic characterization of the bis-oxo complexes 1 and 2 (Figs. 1 ▸ and 2 ▸, formed via alkylperoxo Mn—OOtBu intermediates (Coggins et al., 2020 ▸), further expands the available library of high-valent Mn–oxo dimers (Mullins & Pecoraro, 2008 ▸), demonstrating the stability of the metal–oxo diamond core described previously (Que & Tolman, 2002 ▸).

Structural Commentary
Complex 1
Complex 1 possesses a non-crystallographic C 2 rotation axis and the two Mn centers are crystallographically equivalent across an inversion center (−x, 1 − y, 1 − z). The Mn ion of 1 is in a pseudo-octahedral environment, with small deviations in the O—Mn—N angles relative to an ideal octahedral geometry: O1—Mn1—N1 = 93.76 (12), O1—Mn1—N2 = 92.13 (12), O1—Mn1—N3 = 174.90 (12), and O1—Mn1—N4 = 95.77 (12)°. As is true for all diamond cores, the O1—Mn1—O1′ angle is slightly compressed at 85.53 (12)°. Metrical parameters, Mn1—O1 = 1.829 (3) Å and Mn1—O1′= 1.835 (3) Å (Table 1 ▸) fall within the reported range (1.8 to 1.9 Å) for oxo-bridged MnIV complexes (Krewald et al., 2013 ▸; Mullins & Pecoraro, 2008 ▸; Torayama et al., 1998 ▸). The pyridine nitrogen atoms are outside the typical bonding range, but are oriented towards the Mn ion at distances of Mn1—N1= 2.348 (3) Å and Mn1—N4 = 2.368 (3) Å. Unfavorable steric interactions involving the methyl group at the 6-position of the pyridine arm are likely to be responsible for the longer Mn—N(1,4) distances. Manganese–nitrogen distances involving the amine arms fall within the normal Mn—N range (1.9 to 2.1 Å) for MnIV. The bond involving the tertiary amine [Mn1—N2 = 2.123 (3) Å] is slightly longer than that involving the secondary amine [Mn1—N3 = 2.111 (4) Å]. The Mn1⋯Mn1′ separation of 2.6899 (15) Å, falls within the normal range (2.6 to 2.8 Å) for bis-oxo-bridged MnIVMnIV dimers containing a diamond core. Complex 1 crystallizes with two crystallographically equivalent tetraphenylborate counter-ions and two crystallographically equivalent water molecules. The water molecule is disordered over two sites with site occupancies refined to 0.870 (12) and 0.130 (12) for O2 and O2B respectively, with the applied constraint that both together give 100% occupancy.

Complex 2
Complex 2 also sits on an inversion center (1 − x, 2 − y, 1 − z), making the two Mn atoms crystallographically equivalent. There is disorder in the position of the propyl linker carbon atoms (C1, C2, C3). The site occupancies of N3, C1–C3 and N3B, C1B–C3B refined to 0.804 (5) and 0.196 (5), respectively, with the constraint of both together giving 100% occupancy. The Mn ion of 2 is again in a pseudo-octahedral environment, with small deviations in O—Mn—N angles relative to ideal octahedral geometry: O1—Mn1—N1 = 106.39 (7), O1—Mn1—N2 = 174.90 (7), O1—Mn1—N3 = 89.11 (13), and O1—Mn1—N4 = 103.70 (6)°. Again, as is true for all diamond cores, the O1—Mn1—O1′ angle of 2 is slightly compressed at 85.98 (7)°, and is similar to that in 1. Metrical parameters, Mn—O1 = 1.8325 (15) and Mn—O1′ = 1.8349 (15) Å, are also similar to those found in 1, and fall within the reported range (1.8 to 1.9 Å) for oxo-bridged MnIV complexes. The pyridine nitrogen atoms are once again further from the Mn ions than expected for a formal Mn—N bond, but are oriented towards Mn at distances of Mn1—N1 = 2.3251 (18) Å and Mn1—N4 = 2.3522 (18) Å. This bond elongation is likely to be due to steric interference from the methyl groups at the 6-position of the pyridine rings. The nitrogens on the amine arms are much closer to the Mn center, and fall within the normal Mn—N range (1.9 to 2.1 Å) for MnIV. The Mn—N distance involving the tertiary amine [Mn1—N2 = 2.1828 (18) Å] is noticeably longer than that involving the secondary amine [Mn1—N3= 2.133 (6) Å]. The large difference between these bond lengths in 2, relative to those of 1, likely reflects the increased flexibility of the propyl linker in 2. The Mn1—Mn1′ distance [2.6825 (7) Å] in 2 is essentially the same as that found in 1, and falls within the normal range (2.6 to 2.8 Å) for bis-oxo-bridged MnIVMnIV dimers containing a diamond core. Complex 2 crystallizes with two tetraphenylborate counter-ions and two diethyl ether molecules per cation.
Database survey
The structures of 1 and 2 are analogous to other reported MnIVMnIV(μ-O)2 dimers. The Mn1—Mn1′ distances of 2.6899 (15) Å in 1 and 2.6825 (7) Å in 2 are comparable to other literature examples (Krewald et al., 2013 ▸; Mullins & Pecoraro, 2008 ▸; Torayama, et al., 1998 ▸). The Mn—O bond lengths of 1.829 (3) and 1.835 (2) Å for 1 and 1.8350 (15) and 1.8325 (15) Å for 2 are also similar to literature reported values for MnIVMnIV(μ-O)2 dimers (Krewald et al., 2013 ▸; Mullins & Pecoraro, 2008 ▸; Torayama et al., 1998 ▸). The octahedral geometry of the Mn centers of both structures are very similar in terms of bond angles, all of which are close to the ideal 90 and 180°. The similarities in bond lengths and angles show that 1 and 2 contain a metal–oxo diamond core motif, previously observed in manganese, iron and copper complexes (Que & Tolman, 2002 ▸).
Synthesis and crystallization
General methods
All syntheses were performed using Schlenk-line techniques or under an N2 atmosphere in a glovebox. Reagents and solvents were purchased from commercial vendors, were of highest available purity and were used without further purification unless otherwise noted. MeOH (Na), MeCN (CaH2), and CH2Cl2 (CaH2) were dried and distilled prior to use. Et2O was rigorously degassed and purified using solvent purification columns housed in a custom stainless steel cabinet and dispensed by a stainless steel Schlenk-line (GlassContour). Complexes 3 and 4 were synthesized as described by Coggins et al. (2020 ▸).
Synthesis of 1 and 2
The addition of 1.5 equivalents of tBuOOH to CH2Cl2 solutions of alkoxide-ligated 3 and 4 in an anaerobic cell at room temperature results in the formation of 1 and 2, respectively. Single crystals of the isolated compounds in the form of brown plates for 1 and purple plates for 2 were obtained in up to 40% yield via slow evaporation and crystallization from CH2Cl2. Both reactions result in the loss of the Schiff-base arm present in the starting MnII complexes 3 and 4, most probably because the reactions were performed in moist air (Coggins et al., 2020 ▸).
Refinement
Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. Scattering factors are taken from Waasmaier & Kirfel (1995 ▸). Hydrogen atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with C—H distances in the range 0.95–1.00 Å. Isotropic displacement parameters U eq were fixed at 1.2U eq(C) or 1.5U eq(C-methyl). For the disordered water molecule in complex 1, the water was set-up as a rigid group free to rotate and move during refinement, with DFIX restraints between O and H and between both H per water. The displacement parameters of O2 and O2B were made the same with the EADP constraint. Hydrogen-atom isotropic displacement parameters were fixed at 1.5 times that of the water oxygen atoms. For the disorder in complex 2, the geometry of both groups was set to be similar with the ‘SAME’ option. Displacement parameters of N3-N3B, C1-C1B, C2-C2B, and C3-C3B were restrained with the SIMU command at 0.005 strength.

| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |

R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

| Experimental. 20 seconds exposure, 0.5 degree steps, 40mm distance |
| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
