Publication Metadata only Electrostatic repulsion between the cations of (1-methyl-1H-imidazole-κN3)(2,2′:6′,2′′-terpyridine-κ3N,N′,N′′)platinum(II) perchlorate nitromethane monosolvate prevents Pt⋯Pt interactions(Crystallographic Communications, 2011-08) Akerman, Matthew.; Akerman, Kate.; Jaganyi, Deogratius.; Reddy, Desigan.The reaction between [Pt(terpy)Cl]·2H2O (terpy = 2′,2′′:6′,2′′-terpyridine) and 1-methylimidazole (MIm) in the presence of two equivalents of AgClO4 in nitromethane yields the title compound, [Pt(C15H11N3)(C4H6N2)](ClO4)2·CH3NO2. The dicationic complexes are arranged in a staggered configuration. The torsion angle subtended by the 1-methylimidazole ring relative to the terpyridine ring is 114.9 (5)°. Intermolecular C—H⋯O interactions between the perchlorate anions and the H atoms of the terpy ligand are observed. Consideration of related phenylbipyridyl complexes of platinum(II), which are monocationic, leads to the conclusion that the electrostatic repulsion between the dicationic chelates prevents the formation of Pt⋯Pt interactions. These interactions are a common feature associated with the monocationic species.
