A Polymeric Platinum(II)−Thallium(I) Complex Stabilized by Alkynyl−Thallium and Platinum−Thallium Bonding Interactions

Abstract

The anionic mixed species [trans-Pt(C6F5)2(C⋮CtBu)2]2- reacts with TlNO3 to yield the heteropolymetallic compound [PtTl2(C6F5)2(C⋮CtBu)2] (2). The X-ray crystal structure of its adduct {2(acetone)2}n shows its polymeric nature, giving the first example of a polymeric Pt(II)−Tl(I) complex stabilized by alkynyl−thallium and platinum−thallium bonding interactions. In the solid state, both 2 and the precursor (NBu4)2[trans-Pt(C6F5)2(C⋮CtBu)2] (1) exhibit photoluminescence at room temperature.
