Optical dσ* metal-to-ligand charge transfer of [Re2Br2(CO)6(Se2Ph2)]
Abstract
The binuclear complex [Re2Br2(CO)6(Se2Ph2)] shows an absorption at λmax= 434 nm (in CH2Cl2) which is assigned to a MLCT (metal-to-ligand charge transfer) transition from ReI to the σ*(Se–Se) orbital of the bridging diphenyl diselenide ligand.
