1,3-Bis(3-tert-butyl-2-hy­droxy-5-meth­oxy­benz­yl)hexa­hydro­pyrimidin-5-ol monohydrate

The asymmetric unit of the title compound, C(28)H(42)N(2)O(5)·H(2)O, consists of one half of the organic mol­ecule and one half-mol­ecule of water, both of which are located on a mirror plane which passes through the central C atoms and the hydroxyl group of the heterocyclic system. The hydroxyl group at the central ring is disordered over two equally occupied positions. The six-membered ring adopts a chair conformation, and the 2-hy­droxy­benzyl substituents occupy the sterically preferred equatorial positions. The aromatic rings make dihedral angles of 75.57 (9)° with the mean plane of the heterocyclic ring. The dihedral angle between the two aromatic rings is 19.18 (10)°. The mol­ecular structure features two intra­molecular phenolic O—H⋯N hydrogen bonds with graph-set motif S(6). In the crystal, mol­ecules are connected via O—H⋯O hydrogen bonds into zigzag chains running along the a-axis direction.
