By the reaction of bidentate ligand 1,1'-bis(diphenylphosphino)-ferrocene (dppf) with MoCl_4(CH_3CN)_2, a novel bonding type complex (MoCl_4)2_· (dppf) was synthesized and characterized by elemental analyses,...By the reaction of bidentate ligand 1,1'-bis(diphenylphosphino)-ferrocene (dppf) with MoCl_4(CH_3CN)_2, a novel bonding type complex (MoCl_4)2_· (dppf) was synthesized and characterized by elemental analyses, ^(31)p-NMR, IR and electronic spectra, TG and ICP-AES.
