(E)-1-[4-(2,4-Dihydroxybenzylidene-Amino)Phenyl]Ethanone Sesquihydrate

Abstract

The asymmetric unit of the title compound, C15H13NO3·1.5H2O, consists of one ethanone mol-ecule, one water mol-ecule and one half-mol-ecule of water. The organic mol-ecule is a phenol-imine tautomer, as evidenced from C - O, C - N and C - C bond lengths and it is stabilized by an intra-molecular O - H⋯N hydrogen bond which generates an S(6) ring motif. It is nearly planar, with a dihedral angle of 1.40 (10)° between the two aromatic rings. Mol-ecules are linked by three inter-molecular O - H⋯O hydrogen bonds, forming dimers, and are further linked by C - H⋯π inter-actions, forming a three-dimensional network. © International Union of Crystallography 2007.
