Synthesis, structure and redox chemistry of the aminoallenylidene complex [Mo{CCC(Me)NEt2}(dppe)(η-C7H7)][BPh4]

Spectroelectrochemical IR investigations on the aminoallenylidene complex [Mo{CCC(Me)NEt2}(dppe)(η-C7H7)][BPh4], [1]+, indicate that a reversible one-electron oxidation to the 17-electron radical dication [1]2+ results in an enhancement in the iminium alkynyl character of the ligand.147
