Polymorphs with Varying Platinum(II)−Thallium(I) Interactions

Abstract

TlI[(C4H9N4)PtII(CN)2] forms a red, crystalline polymorph in which the ions are arranged to form an extended ...Pt...Tl...Pt...Tl... chain (Pt...Tl distance, 3.0978(2) A; Pt-Tl-Pt and Tl-Pt-Tl angles, (171.37(2) degrees ) and a yellow polymorph in which dimers are connected by pairs of Pt...Tl interactions with a Pt...Tl distance of 3.0256(5) A.
