Isovalent and Mixed‐Valent Ylide Complexes of Gold: The Synthesis of Trinuclear Compounds Having Double Paddlewheel Structure

Abstract

The first organo trigold complex, the title compound 1, X = CL, Br, I, is characterized by several unique structural features. In 1, AuIII serves as a spiro atom; its square-planar coordination is expanded to a pseudooctahedral coordination by two flanking Au I centers. Complex 1 is colorless and air-stable.
