Cocrystallization of two tautomers: 4-(1-{[4-(dimethyl-amino)benzyl-idene]- hydrazono}eth-yl)benzene-1,3-diol and 6-[(E)-1-{[4-(dimethyl-amino)benzyl-idene] -hydrazino}ethyl-idene]-3-hy-droxy-cyclo-hexa-2,4-dien-1-one (1/1)

Two different tautomeric forms of a new Schiff base, C17H19N3O2· C17H19N3O2, are present in the crystal in a 1:1 ratio, namely the enol-imine form 4-(1-{[4-(dimethyl-am-ino)benzyl-idene]-hydra-zono}-eth-yl)benzene-1,3-diol and the keto-amine form 6-[(E)-1

Synthesis, characterization and crystallographic studies of 4-{(1E)-1-[(2E)-{[4-(dimethylamino)phenyl] methylidene}hydrazono]ethyl}benzene- 1,3-diol

The title compound 4-{(1E)-1-[(2E)-{[4-(dimethylamino)phenyl]methylidene} hydrazono]ethyl}benzene-1,3-diol (1) which is an azine moiety, has been synthesized by microwave irradiation technique. The characterization by IR and mass spectroscopy confirms the structure of (1). The crystal system, lattice parameters and molecular structure of (1) has been determined by single crystal X-ray diffraction technique. The crystallographic data for the compound (1) is being reported for the first time. Studies reveal that the compound exhibits intermolecular and intramolecular hydrogen bonding interactions in its crystal structure. The compound crystallizes in the monoclinic space group P21/n with unit cell dimensions a = 11.8734(7) A; b = 9.6194(6) A; c = 27.2410(16) A; β = 96.435(3) A; V = 3091.7(3) A3 and D calc = 1.278 Mg/m3 for Z = 8. The surface morphology of the crystalline compound has been studied by SEM analysis. SEM reveals the microcrystalline features of the compound under study.
