Abstract

The binuclear compound [(triphos)RhH(μ-H)2Cu(diphos*)]+ with triphos = CH3C(CH2PPh2)3 and diphos* = o-C6H4(CH2P(C6H11)2)2 has been prepared and characterized. It crystallizes as [CF3SO3] salt in the monoclinic P21/c space group with Z = 4, a = 13.802(4)Å, b = 19.462(4)Å, c = 26.604(5)Å, β = 99.8(3)°, and V = 7041(3)Å3. The structure of the complex consists of two metal fragments with hydride ligands bridging the Rh-Cu contact. The hydride ligands were not located by X-rays but, from the arrangement of the heavy atoms and by methods of potential energy, the most probable positions of two hydride ligands bridging the Rh-Cu interaction and one that remains terminal on the rhodium atom, were obtained.
