Abstract

Abstract The crystal structures of hydrates of five substituted benzaldehyde (pyrazinecarbonyl)hydrazone derivatives [N2C4H3CONHN=CHC6H5-n X n · m H2O: m = 1, n = 1, X = 3-HO; m = 1, n = 2, X2 = 2,5-(HO)2; m = 1, n = 2, X2 = 2,4-(MeO)2; m = 2.5, n = 2, X2 = 3,4-(MeO)2; m = 3, n = 1, X = 4-HO] are reported. In all cases the water molecules participate in strong hydrogen-bonds extending and partially replacing the weak intermolecular C–HX (X = O, N or π-ring) hydrogen-bonding and π · · · π interactions normally present in anhydrous structures of compounds of this type.
