1,5-Bis[1-(2-hydroxyphenyl)ethylidene]carbonohydrazide dimethylformamide monosolvate

L. Du and W. Zhang

Abstract: In the title compound, C₁₇H₁₈N₄O₃·C₃H₇NO, the main disubstituted urea and solvate molecules are linked by pairs of N-HO hydrogen bonds. In the main molecules, the benzene rings form a dihedral angle of 15.59 (13)° a;nd two intramolecular O-HN hydrogen bonds influence the molecular conformation. In the crystal structure, weak intermolecular C-HO interactions link the hydrogen-bonded pairs into chains along the b axis. The chains associate via C-H interactions.
