Abstract

A new N,O-bischelator-bridged dirhenium(I) metallacycle, [Re2(CO)6(μ-η4-mpdo)(μ-4,4�-tmdp)] (1, H2mpdo = 2-methylpyrimidine-4,6-diol, 4,4�-tmdp = 4,4�-trimethylenedipyridine) has been self-assembled in a one-pot reaction in p-xylene at 140 °C. Compound 1 displays unusual multiple phosphorescence emissions at room temperature; an emission quantum yield of 0.26�0.03 and triexponential decay with an average radiative decay constant of 0.052 μs (λmax = 342 nm) were determined. These results as well as those of DFT/ TDDFT calculations confirmed the nature of the emitting states.
