Abstract

Treatment of [Cu2(dcpm)2]Y2 (dcpm = bis(dicyclohexylphosphino)methane, Y = ClO4-, BF4-, PF6-, CF3SO3-) with refluxing MeOH in the presence of KOH afforded hydride complexes [Cu3(dcpm)3(mu3-H)]Y2 (1) in about 85% yield. Refluxing [Cu2(dcpm)2](PF6)2 with MeOH in the presence of NH3.H2O and air gave a carboxylate complex [Cu2(dcpm)2(O2CCH2OH)]PF6 (2) in 40% yield. All of the complexes 1 and 2 have been characterized by X-ray crystallography. The Cu3 cores in 1 are almost perfectly shielded by the dcpm ligands. Intense photoluminescence was observed for 1 both in the solid state and in solution.
