Abstract


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,  (C19H15N3O2S2.C3H7NO), 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) Å, 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.
