Synthesis, crystal structure and Hirshfeld surface analysis of 5,5-diphenyl-2-[2-(propan-2-ylidene)hydrazin-1-yl]-4,5-dihydro-1<i>H</i>-imidazol-4-one <i>N</i>,<i>N</i>-dimethylformamide hemisolvate
The asymmetric unit of the title structure, 2C<sub>18</sub>H<sub>18</sub>N<sub>4</sub>O<sub>2</sub>·C<sub>3</sub>H<sub>7</sub>NO, consists of two independent mol-ecules of the substituted imidazolone having different conformations, and one mol-ecule of solvent DMF. The two imidazolone mol-ecules are linked by N-H⋯N and C-H⋯O hydrogen bonds and the DMF is joined to one of these by an N-H⋯O hydrogen bond. Additional N-H⋯N and C-H⋯O hydrogen bonds link these groups into corrugated layers parallel to the (101) plane with the layers joined by C-H⋯π (ring) inter-actions. A Hirshfeld surface analysis indicated that H⋯H inter-actions account for over half of the inter-molecular contacts.
