2-Hydroxy-(2-methyl-1H-indol-3-ylmethylidene)benzohydrazide ethanol solvate

W. A. Yehye, A. Ariffin and S. W. Ng

Abstract: In the title compound, C₁₇H₁₅N₃O₂·C₂H₆O, Schiff base molecules are linked by a hydroxy-amido hydrogen bond into a helical chain running along the b axis. This chain is consolidated by two other hydrogen bonds; the ethanol solvent molecule is a hydrogen-bond donor to the amide group and a hydrogen-bond acceptor for the indolyl NH group of an adjacent Schiff base molecule.
