Crystal structure and Hirshfeld surface analysis of (E)-1-[(4,7-di-methyl-quinolin-2-yl)methyl-idene]semicarbazide dihydrate.

In the title compound, C(13)H(14)N(4)O·2H(2)O, the organic mol-ecule is almost planar. In the crystal, the mol-ecules are linked by O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonds, forming a two-dimensional network parallel to (10). 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%) inter-actions.
