2,2':6',2''-Terpyridine(1-methylimidazole-N³)platinum(II) Perchlorate Acetonitrile Solvate

The title compound, [Pt(C₁₅H₁₁N₃)(C₄H₆N₂)](ClO₄)₂.C₂H₃N, is formed by reaction of chloro-2,2′:6′,2′′-terpyridine­platinum(II) chloride dihydrate with 1-methylimidazole in the presence of excess amounts of NaClO₄. The platinum center is approximately square-planar N₄– coordinated to the tridentate terpyridine and monodentate 1-methylimidazole with Pt-N 1.943 (7)–2.026 (7) Å. The imidazole ring forms a dihedral angle of 66.5 (2)° with the planar Pt–terpyridine ring system. The crystal packing is dominated by π-π stacking interactions with the absence of any short metal...metal interactions.
