Crystal structure of 1,3-bis­(3-tert-butyl-2-hy­droxy-5-methyl­benz­yl)-1,3-diazinan-5-ol monohydrate

The asymmetric unit comprises one 1,3-bis­(3-tert-butyl-2-hy­droxy-5-methyl­benz­yl)-1,3-diazinan-5-ol mol­ecule and one water mol­ecule. The two mol­ecular components are held together through an O—H⋯O hydrogen bond.

Abstract

In the title hydrate, C₂₈H₄₂N₂O₃·H₂O, the central 1,3-diazinan-5-ol ring adopts a chair conformation with the two benzyl substituents equatorial and the lone pairs of the N atoms axial. The dihedral angle between the aromatic rings is 19.68 (38)°. There are two intra­molecular O—H⋯N hydrogen bonds, each generating an S(6) ring motif. In the crystal, classical O—H⋯O hydrogen bonds connect the 1,3-diazinane and water mol­ecules into columns extending along the b axis. The crystal structure was refined as a two-component twin with a fractional contribution to the minor domain of 0.0922 (18).

Chemical context  

Current research of our group is directed toward the synthesis of cyclic aminals with conformational inter­est, which may have the structural requirement for hydrogen-bonded inter­actions. Obvious targets are the 5-hy­droxy-1,3-diazinanes because a hydroxyl group in the six-membered 1,3-di­aza­cyclic ring may alter the conformational preferences resulting from the inter­actions of the hydroxyl group and the endocyclic nitro­gen atoms (Salzner, 1995 ▸). We gradually realized that the structural features of this class of compounds are much more complex than previously believed and defined. Thus, we intend to use X-ray investigations to complement the information on conformational preferences and electronic parameters of 5-hy­droxy-1,3-diazinanes obtained using NMR chemical shift data, spin–spin coupling constants, and their NOESY spectra.

We have previously reported the synthesis and crystal structure of 1,3-bis­(3-tert-butyl-2-hy­droxy-5-meth­oxy­benz­yl)-1,3-diazinan-5-ol monohydrate (II) and this study has shown that the hydroxyl substituent on the 1,3-diazinane ring is disordered over two positions, namely one component equatorial and the other axial (Rivera et al., 2014 ▸). As a logical step in the progression of these studies, in this paper we discuss the synthesis and crystal structure of the title compound (I), 1,3-bis­(3-tert-butyl-2-hy­droxy-5-methyl­benz­yl)-1,3-diazinan-5-ol monohydrate. The X-ray study again reveals that compound crystallizes with a solvent water mol­ecule that links to the organic mol­ecule through an O—H⋯O hydrogen bond. Furthermore, the hydroxyl group in the pyrimidine ring is also disordered over two positions (axial, equatorial).

Structural commentary  

The mol­ecular structure of the title compound is presented in Fig. 1 ▸. The structure consists of a 1,3-bis­(3-tert-butyl-2-hy­droxy-5-methyl­benz­yl)-1,3-diazinan-5-ol mol­ecule and a water mol­ecule. These components are connected by an O3—H3⋯O1W hydrogen bond (Table 1 ▸) with the water-O atom as the acceptor. The 1,3-diazinane ring adopts a chair conformation with puckering parameters: Q = 0.588 (2) Å, θ = 176.9 (5) and φ = 245 (9)°. Atoms N1 and N2 are essentially tetra­hedral (bond-angle sums are 331.5° for N1 and 331.6° for N2), with their benzyl substituents in equatorial positions and the lone pairs axial. The aromatic rings of these substituents are roughly parallel, with a dihedral angle between the two benzene rings of 19.7 (4)°. Intra­molecular O—H⋯N hydrogen bonds form between the pyrimidine N atoms and the OH groups of the benzyl substit­uents and the pyrimidine N atoms, each with an S(6) graph-set motif (Table 1 ▸). These inter­actions stabilize the mol­ecular conformation, with O1⋯N1 = 2.696 (5) and O2⋯N2 = 2.702 (5) Å. These distances are closely comparable to those observed in the related structure (II) (Rivera et al., 2014 ▸).

The N2—C7 distance of 1.485 (6) Å is slightly longer than the typical value for an N—C bond [1.469 Å]. The remaining C—N bonds in the mol­ecule are also typical and compare well with those found in the the related structure (II) (Rivera et al., 2014 ▸). The C12—O1 and C22—O2 distances are typical of those for a hy­droxy substituent on an aromatic ring [1.376 (6) and 1.374 (5) Å, respectively]. Bond angles within the 1,3-diazinane ring are unexceptional. The hydroxyl group is disordered over two positions, with site occupancies refining to 0.794 (13) and 0.206 (13). The OH group of the major component is in the equatorial position with the minor component axial.

Supra­molecular features  

In the crystal, O3—H3⋯O1W hydrogen bonds form chains along b. These contacts are augmented by additional strong O1W—H1WA⋯O3 hydrogen bonds, this time with O3 as the acceptor (Fig. 2 ▸, Table 1 ▸). The chains are held together by van der Waals forces.

Database survey  

Apart from the previously published structure (Rivera et al., 2014 ▸), there is only one similar entry in the CSD (Mendes et al., 2014 ▸). In this latter structure, the 1,3-diazinane mol­ecule acts as a ligand to an iron(III) cation, which would affect comparisons with the geometric parameters of the title compound.

Synthesis and crystallization  

The title compound was prepared according to our reported method (Rivera et al., 2016 ▸). The crude product was recrystallized from hexane solution, giving colorless crystals suitable for X-ray diffraction. M.p. 400 K, yield, 38%.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The O3—H3 hydroxyl group is disordered over two positions, one with the OH group equatorial with the minor component axial. The site occupancies refine to 0.794 (13) and 0.206 (13), respectively. The H atom of the hydroxyl group of the major component was located in a difference map and refined freely while that of the minor component was fixed geometrically, both with U _iso(H) set to 1.2U _eq(O). The H atoms of the water mol­ecule were fixed in their found locations with U _iso(H) set to 1.5U _eq(O). C-bound H atoms were fixed geometrically (C—-H = 0.95 or 0.99 Å) and refined using a riding-model approximation, with U _iso(H) set to 1.2U _eq of the parent atom. The crystal was a two-component twin with a fractional contribution to the minor domain of 0.0922 (18).

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.

Refinement. Refined as a 2-component twin.
