1,5-Bis[(E)-1-(2-hydroxy-phen-yl)ethyl-idene]carbonohydrazide dimethyl sulfoxide solvate.

ABSTRACT: The title dimethyl sulfoxide (DMSO) solvate, C(17)H(18)N(4)O(3)·C(2)H(6)OS, shows the disubstituted urea derivative to adopt an almost planar geometry (r.m.s. deviation for non-H atoms = 0.132?Å); the mol-ecule has non-crystallographic twofold mol-ecular symmetry. This conformation is stabilized by two intra-molecular O-H?N hydrogen bonds. The components of the crystal are connected by N-H?O hydrogen bonds, whereby both amine H atoms are connected to a DMSO O atom, and C-H?O contacts involving the DMSO H and urea carbonyl atoms, forming a supra-molecular chain along the c axis. The chains associate via C-H?? inter-actions.
