Abstract: Crystallization of chloro(2,2':6',2''-terpyridine)platinum(II) chloride from dimethyl sulfoxide yields a red polymorph, [PtCl(C₁₅H₁₁N₃)]Cl·C₂H₆OS, (I), which exhibits stacking along the a axis through pairs of PtPt(-x, -y, -z) interactions of 3.3155 (8) Å. The cations are further associated through close PtPt(1 - x, -y, -z) distances of 3.4360 (8) Å. Recrystallization from water gives a merohedrally twinned yellow-orange dihydrate form, [PtCl(C₁₅H₁₁N₃)]Cl·2H₂O, (II), with pairwise short PtPt(1 - x, 2 - y, -z) contacts of 3.3903 (5) Å but no long-range stacking through the crystals. Interpair PtPt(-x, 2 - y, -z) distances between cation pairs in the hydrate are 4.3269 (5) Å.

Formula: [PtCl(C₁₅H₁₁N₃)]Cl·C₂H₆OS and [PtCl(C₁₅H₁₁N₃)]Cl·2H₂O
