Abstract

The asymmetric unit of the title structure, 2C18H18N4O2·C3H7NO, 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.
