6,6'-Dieth-oxy-2,2'-[4,5-dimethyl-o-phenyl-enebis(nitrilo-methyl-idyne)]diphenol-ethanol-water (1/1/1).

ABSTRACT: The title bis-Schiff base compound, C(26)H(28)N(2)O(4)·C(2)H(6)O·H(2)O, crystallizes as an ethanol and water solvate. Strong intra-molecular O-H?N hydrogen bonds generate S(6) ring motifs. The water H atoms form bifurcated O-H?(O,O) inter-molecular hydrogen bonds with the O atoms of the hydroxyl and eth-oxy groups with R(1) (2)(5) ring motifs, which may, in part, influence the mol-ecular configuration. The dihedral angles between the central benzene ring and the two outer benzene rings of the Schiff base mol-ecule are 5.64?(8) and 44.78?(9)°. The crystal structure is further stabilized by inter-molecular C-H?O and ?-? inter-actions [centroid-centroid distances = 3.6139?(11)-3.7993?(11)?Å].
