spectra for all three bear a remarkable similarity to that of the trans-M(cyclam)(CN)2+ cations. The trifluoropropynyl complex of Co3+ shows electrochemical behavior nearly identical with that of its dicyano analogue. Metal-centered phosphorescence from the Rh(III) complex in room-temperature aqueous solution has a quantum yield of 0.12 and a lifetime of 73 μs, nearly 10 times higher than those of its dicyano
