Synthesis and X-Ray Structure of a Heterovalent, Cycloaurated Pentafluorophenylgold(I)/Pentafluorophenylgold(III) Complex

Abstract

The heterovalent gold(I)/gold(III) complex [(C₆F₅)Au^I(μ-2-Ph₂PC₆H₃-6-Me)Au^III(C₆F₅){η²-(6-MeC₆H₃-2-PPh₂)}] has been prepared and structurally characterized by X-ray crystallography. It shows square planar stereochemistry at Au^III incorporating a four-membered chelate ring and linear arrangement at Au^I. The compound is a rare example of a heterovalent complex containing an aryl ligand on each gold atom.
