Gold Complexes with Selenium Ligands, II [1] Preparation and Crystal Structures of the Gold Diphenylselenide Complexes Ph2SeAuCl and Ph2SeAuCl3

Abstract

The complexes Ph2SeAuCl (green) and Ph2SeAuCl3 (brown) are prepared by direct reaction between the diphenylselenide ligand and the corresponding gold chloride. The crystal structures confirm the presence of monomeric, linear (AuI) or square planar (AuIII) coordinated complexes with bond lengths A u(I)-Se 2.378(1), Au(III)-Se 2.445(1) Å. Short non-bonded contacts Au(I) ··· Au(I) and Au(III) ··· Cl are observed.
