Synthesis and structure of 4,5-diphenyl-1H-imidazol-3-ium thio-cyanate.

In the title mol-ecular salt, C15H13N2 +·SCN-, the dihedral angles between the imidazole ring and pendant phenyl groups are 51.61 (14) and 35.47 (15)°. In the crystal, the ions are linked by N-H⋯N and C-H⋯S hydrogen bonds, forming R 4 2(16) loops. These units are further connected by C-H⋯π and C-S⋯π inter-actions into a three-dimensional supra-molecular network. Hirshfeld surface analysis of the imidazolium cation shows that H⋯H (42.9%), C⋯H/H⋯C (34.9%), N⋯H/H⋯N (10.7%) and H⋯S/S⋯H (6.5%) contacts are the major contributors to the crystal packing.
