Abstract
The polymeric title compound, poly[aquahemi[μ2-3,6-bis(pyrimidin-2-yl)-1,4-dihydro-1,2,4,5-tetrazine](μ3-sulfato)cadmium(II)], [Cd(SO4)(C10H8N8)0.5(H2O)]n, (I), represents an example of a three-dimensional coordination polymer resulting from the reaction of CdSO4·8/3H2O with 3,6-bis(pyrimidin-2-yl)-1,4-dihydro-1,2,4,5-tetrazine (H2bmtz, C10H8N8) under hydrothermal conditions. The CdII atom has a distorted octahedral coordination environment defined by two nitrogen atoms from one H2bmtz ligand, three oxygen atoms from three different sulfate anions, and one oxygen atom from a coordinating water molecule. The 1,4-dihydro-1,2,4,5-tetrazine ring of the H2bmtz ligand is located about an inversion center, with the NH group being equally disordered over two sites. The sulfate anion acts as a μ3-bridging ligand to connect three CdII atoms, resulting in the formation of [Cd(SO4)(H2O)] sheets propagating parallel to the bc plane. Adjacent sheets are interconnected across the H2bmtz ligands, which coordinate the CdII atoms in a bis-bidentate coordination mode, to form a three-dimensional framework structure. The framework is further stabilized by classical O—H⋯O hydrogen bonds involving the coordinating water molecules and the sulfate groups, and by N—H⋯O hydrogen bonds between the disordered tetrazine NH groups and sulfate oxygen atom, along with C—H⋯π and π–π stacking [centroid-to-centroid separation = 3.5954 (15) Å] interactions between parallel pyrimidine rings of the H2bmtz ligand.
Chemical context
Coordination polymers (CPs) are a class of organic–inorganic hybrid materials formed from metal ions or metal clusters and organic linkers through covalent bonds. The structural organization of CPs can result in chains, sheets or three-dimensional frameworks (Batten et al., 2009 ▸). These hybrid materials have received extensive attention over the past three decades owing to their structural features and useful applications in the fields of gas storage and separation, catalysis, chemical sensing, magnetism or proton conduction (Furukawa et al., 2010 ▸; Ye & Johnson, 2016 ▸; Espallargas & Coronado, 2018 ▸; Xu et al., 2016 ▸; Zhang et al., 2017 ▸). Nowadays, many multi-dimensional CPs with structural and topological diversity have been synthesized through the tremendous possibilities of choices for building blocks, and some of them seem promising as candidate materials, for instance, in gas purification (Duan et al., 2015 ▸). In the context of the crystal engineering of CPs, the most feasible strategy for the construction of such infinite hybrid networks is by the careful selection of metal coordination arrangements and suitable organic linkers. Among the most common ligands, the rigid organic carboxylate- and pyridyl-based ligands have by far been the most widely used to control the structural motifs of these solids (Glöckle et al., 2001 ▸).
In this work, to explore the synthesis of novel CPs using 3,6-bis(pyrimidin-2-yl)-1,4-dihydro-1,2,4,5-tetrazine, C10H8N8 or H2bmtz (Kaim & Fees, 1995 ▸; Chainok et al., 2012 ▸) as a polydentate nitrogen-donor ligand with cadmium(II) sulfate, a new CP [Cd(SO4)(H2bmtz)0.5(H2O)]n (I) was isolated under hydrothermal conditions. The crystal structure and supramolecular interactions of (I) are reported herein.
Structural commentary
The asymmetric unit of the title compound consists of one CdII cation, one-half of the H2bmtz ligand, one sulfate anion and one coordinating water molecule. The 1,4-dihydro-1,2,4,5-tetrazine ring of the H2bmtz ligand is located about an inversion centre, with the NH group (N4) being equally disordered over two sites. As shown in Fig. 1 ▸, the CdII atom exhibits a distorted octahedral [CdN2O4] coordination environment with two nitrogen atoms from the H2bmtz ligand, three oxygen atoms from three different sulfate anions and one oxygen atom from the coordinating water molecule. The bond angles around the central CdII atom range from 69.69 (5) to 168.46 (5)°. The Cd—O and Cd—N bond lengths fall in the range of 2.2321 (12)–2.3790 (13) Å, which is comparable with those of reported cadmium(II) sulfate compounds containing additional nitrogen donor ligands such as [Cd2(SO4)2(C16H12N6)2(H2O)2]·4H2O (GADLON; Harvey et al., 2003 ▸), [Cd2(C2H3O2)2(S2O8)(C15H11N2)2(H2O)2]·7H2O (FOMBUF; Díaz de Vivar et al., 2005 ▸) and [Cd2(C15H9N9)(H2O)6(SO4)2]·H2O (DIQCOX; Safin et al., 2013 ▸). The complete H2bmtz molecule is not planar (r.m.s. deviation = 0.111 Å) with the central six-membered ring of the 1,4-dihydro-1,2,4,5-tetrazine moiety in a twist-boat conformation; the C5—N3—N4A i—C5i torsion angle is 36.4 (4)° [symmetry code: (i) 2 − x, 1 − y, 1 − z]. The sulfate anion acts as a μ3-bridging ligand to connect three CdII atoms to form a sheet-like structure of [Cd(SO4)(H2O)] units, propagating parallel to the bc plane, Fig. 2 ▸. Adjacent sheets are interconnected across the H2bmtz ligands, which exhibit a bis-bidentate coordination mode, giving rise to a three-dimensional framework structure, Fig. 3 ▸.

Supramolecular features
In the crystal, classical O—H⋯O hydrogen bonds exist between the coordinating water molecules and the sulfate groups, and N—H⋯O hydrogen bonds involving the disordered tetrazine NH group and sulfate oxygen atoms. In this way, rings with 
(8) and 
(16) graph-set motifs are formed, Table 1 ▸. Additionally, C—H⋯π [H⋯Cg = 3.34 (2) Å; Cg is the centroid of the pyrimidine ring] and π–π stacking [centroid-to-centroid separation = 3.5954 (15) Å, slippage between parallel pyrimidine rings = 1.131 Å] interactions between the pyrimidine rings of the H2bmtz ligand are also observed, Fig. 4 ▸.

Database survey
A search of the Cambridge Structural Database (CSD version 5.41, November 2019 update; Groom et al., 2016 ▸) gave only two hits for H2bmtz complexes with transition metals ions, viz. with CuI (QORNAM; Glöckle et al., 2001 ▸) and AgI (ZASTAQ; Chainok et al., 2012 ▸). In these structures, the coordination mode of the H2bmtz ligands is bis-bidentate through nitrogen atoms.
Synthesis and crystallization
All reagents were of analytical grade and were used as received without further purification. The ligand 3,6-bis(pyrimidin-2-yl)-1,4-dihydro-1,2,4,5-tetrazine was synthesized according to a literature method (Kaim & Fees, 1995 ▸). A mixture solution of CdSO4·8/3H2O (41.7 mg, 0.2 mmol) and the H2bmtz ligand (36.7 mg, 0.1 mmol) in water (5 ml) was added into a 15 ml Teflon-lined reactor, stirred at room temperature for 10 min, sealed in a stainless steel autoclave and placed in an oven. The mixture was heated to 383 K under autogenous pressure for 48 h, and then cooled down to room temperature. After filtration, brown block-shaped crystals were obtained in 80% yield (33.4 mg) based on the cadmium(II) source.
Refinement
Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. Nitrogen atom N4 of the 1,4-dihydro-1,2,4,5-tetrazine ring was found to be disordered about an inversion centre; restraints (SADI and RIGU with esd 0.001 Å2) were used for its refinement. All hydrogen atoms were found in difference-Fourier maps. H atoms attached to C atoms were refined in the riding-model approximation with C—H = 0.93 Å and U iso(H) = 1.2U eq(C). The H atoms bound to O or N atoms were refined with distance restraints of O—H = 0.84 ± 0.01 Å and N—H = 0.86 ± 0.01 Å and with U iso(H) = 1.5U eq(O) and 1.2U eq(N), respectively.

Special details
| 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. |
