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