A novel coordination mode for cationic phosphorus pπ systems: µ2-bridging coordination of a bis(phosphonio)isophosphindolium cation
Abstract
1,3-Bis(triphenylphosphonio)isophosphindolium bromide reacts with CuBr to give a binuclear complex which is shown by X-ray crystallography to contain a µ2(P)-bridging cationic bis(triphenylphosphonio)isophosphindolium ligand.
