Mercury(II) chloride bridging two rhodium atoms. Preparation and X-ray crystal structure of [Rh2(η-C5H5)2(µ-CO)(µ-Ph2PCH2PPh2)(µ-HgCl2)]
Abstract
The title compound has been obtained by treating [Rh2(η-C5H5)2(µ-CO)(µ-dppm)][dppm = bis(diphenylphosphino)methane] with HgCl2, and characterized by spectroscopic and X-ray analyses; it represents the first example of mercury(II) chloride bridging two transition metal atoms in a complex.
