Abstract:
Ethene dissociation from [(Me(n)tpa)Ir-II-(ethene)](2+), induced by coordination of acetonitrile, causes a rapid and selective M-C coupling between Ir-II and Ir-II(ethene), resulting in ethylene-bridged dinuclear iridium(III) complexes of the composition [{(Me(n)tpa)Ir-III-(NCMe)}(2)(mu(2)-C2H4)](4+) (n = 2, 3).
