Crystal structure and Hirshfeld surface analysis of ( E )-2-[2-(2-amino-1-cyano-2-oxo-ethyl-idene)hydrazin-1-yl]benzoic acid N , N -di-methylformamide monosolvate.

In the title compound, C 10 H 8 N 4 O 3 ·C 3 H 7 NO, the asymmetric unit contains two crystallographically independent mol-ecules A and B , each of which has one DMF solvate mol-ecule. Mol-ecules A and B both feature intra-molecular N-H⋯O hydrogen bonds, forming S (6) ring motifs and consolidating the mol-ecular configuration. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect mol-ecules A and B , forming R 2 2 (8) ring motifs. Weak C-H⋯O inter-actions link the mol-ecules, forming layers parallel to the (12) plane. The DMF solvent mol-ecules are also connected to the main mol-ecules ( A and B ) by N-H⋯O hydrogen bonds. π-π stacking inter-actions [centroid-to-centroid distance = 3.8702 (17) Å] between the layers also increase the stability of the mol-ecular structure in the third dimension. According to the Hirshfeld surface study, O⋯H/H⋯O inter-actions are the most significant contributors to the crystal packing (27.5% for mol-ecule A and 25.1% for mol-ecule B ).
