Treatment of 2-diphenylphosphino-6-methylpyridine (dpPyMe) with Cu(CH3CN)4BF4 afforded the stable dinuclear Cu(i) complex [Cu2([small mu ]-dpPyMe)3(CH3CN)](BF4)2. This compound is a weak emitter in solution, however a remarkably high emission quantum yield (46%) has been found in a rigid matrix at room temperature.
