66′-Di-tert-butyl-44′-dimeth­oxy-22′-13-diazinane-13-diylbis(methyl­ene)diphenol 0.19-hydrate

摘要

In the title hexa­hydro­pyrimidine derivative, C28H42N2O4·0.19H2O, the 1,3-diazinane ring has a chair conformation with a diequatorial substitution. The asymmetric unit contains one half-organic mol­ecule and a solvent water mol­ecule with occupany 0.095. The mol­ecule lies on a mirror plane perpendicular to [010] which passes through the C atoms at the 2- and 5-positions of the heterocyclic system. The partially occupied water mol­ecule is also located on this mirror plane. The dihedral angle between the planes of the aromatic rings is 17.71 (3)°. Two intra­molecular O—H⋯N hydrogen bonds with graph-set motif S(6) are present. No remarkable inter­molecular contacts exist in the crystal structure.
