CRYSTAL STRUCTURE OF N-{(1Z)-3-OXO-1-(THIOPHEN-2-YL)-3-[(2E)-2-(THIOPHEN-2-YLMETHYLIDENE)-HYDRAZINYL]PROP-1-EN-2-YL}BENZAMIDE: N,N-DIMETHYLFORMAMIDE (1:1) SOLVATE

Abstract

N -{(1 Z )-3-Oxo-1-(thiophen-2-yl)-3-[(2 E )-2-(thiophen-2-ylmethylidene)hydrazinyl]prop-1-en-2-yl}benzamide: N , N -dimethylformamide (1:1) solvate, (C 19 H 15 N 3 O 2 S 2. C 3 H 7 NO), crystallizes in the monoclinic space group C2/c with the following unit cell parameters: a = 21.111(3), b = 8.7685(8), c = 25.742(3) A, β = 105.273(13) o and Z=8. The crystal structure was solved by direct methods and refined by full matrix least squares procedures to a final R value of 0.0962 for 2155 observed reflections. The crystal structure is stabilized by N–H⋅⋅⋅O and C–H⋅⋅⋅O hydrogen bonds. The DMF solvent gives rise to C10-H10···O3 intermolecular interaction.
