[Bi2(O2CCF3)4]⋅C6Me6—Arene Adduct of a Reduced Main Group Element Carboxylate with Paddle Wheel Structure

Abstract

The first main group dimetal complex with tetragonal-prismatic coordination is [Bi2(O2CCF3)4] (structure depicted), which forms a component of a linear one-dimensional coordination copolymer with hexamethylbenzene molecules. The “paddle wheel” motif well-known from chromium(II) acetate and hundreds of other transition metal complexes is thus introduced into the coordination chemistry of main group elements.
