Crystal structure and Hirshfeld surface analysis of (E)-1-[(4,7-dimethylquinolin-2-yl)methylidene]semicarbazide dihydrate

Abstract

In the title compound, C13H14N4O·2H2O, the organic molecule is almost planar. In the crystal, the molecules are linked by O—H...O, N—H...O and O—H...N hydrogen bonds, forming a two-dimensional network parallel to (10\overline{1}). Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H...H (55.4%), H...O/O...H (14.8%), H...C/C...H (11.7%) and H...N/N...H (8.3%) interactions.
