Synthesis and structure of [Tl(C 6F 5) 2Cl{Au(C 6F 5) 3(PPh 2CH 2PPh 2(O))} 2

Abstract

Two trinuclear gold-thallium-gold complexes, [Tl(C 6F 5) 2X{Au(C 6F 5) 3(PPH 2CH 2PPh 2CH 2PPh 2(O))} 2 (X  C 6F 5, Cl), have been synthesised by reaction of [Au(C 6F 5) 3(PPh 2(O))] with [Tl(C 6F 5) 2Cl] or [Tl(C 6F 5) 3(diox)], in which the phosphine oxide moiety coordinates to thallium; the crystal structure of the former product has been established by X-ray diffraction.
