Isolation of the mixed-metal carbonyl cluster anion [RuIr 3(CO) 9(μ-CO) 3] −. Crystal structure of its bis(triphenylphosphine)iminium salt

Abstract

The anion [RuIr 3(CO) 12] − has been isolated as one of the products from decomposition of [RuIr 4(CO) 15] 2− in the absence of CO, and the structure of the bis(triphenylphosphine)iminium salt has been determined by X-ray diffraction. The anion is isoelectronic and isostructural with CO 4(CO) 12 and Rh 4(CO) 12, with the Ru atom located at one vertex of the metal triangle, which bears three edge-bridging carbonyls.
