Abstract

In the title compound, [Pt(C17H19N4)Cl], the PtII cation is C,C′,C′′-chelated by the 1,1′-(5-methyl-1,3-phenylene)bis(3,5-dimethyl-1H-imidazolylidene) anion and coordinated by a Cl− anion in a distorted square-planar coordination geometry. π–π stacking is observed between nearly parallel imidazole and benzene rings of adjacent molecules, the centroid–centroid distance being 3.802 (4) Å.
