Two type skeleton heterobimetallic trinuclear Cu–Mo–S clusters containing closo carborane diphosphine ligand 1,2-bis(diphenylphosphino)-1,2-dicarba-closo-dodecaborane

The carborane skeleton was introduced into the heterometallic sulfide cluster cores. Two heterobimetallic trinuclear Cu–Mo–S clusters with linear or butterfly-shaped skeleton containing 1,2-bis(diphenylphosphino)-1,2-dicarba-closo-dodecaborane have been synthesized by the reactions of (NH4)2MoS4 or (NH4)2MoOS3, CuSCN with 1,2-(PPh2)2-1,2-C2B10H10 (L) in dichloromethane and characterized by elemental analysis, FT-IR, UV/Visible, 1H and 13C NMR spectroscopy and X-ray structure determination.
