| Abstract: | Solvothermal synthesis method has been successfully introduced into the diphosphine carborane system, and two new nickel complexes
containing nido-carborane diphosphine ligand 7,8-(PPh2)2-7,8-C2B9H10]− with the formula Ni2(μ-Cl)(μ-OOPPh2){7,8-(PPh2)2-7,8-C2B9H10}2]·CH2Cl2 (1) and H3O]NiBr2] {7,8-(PPh2)2-7,8-C2B9H10}·C6H6 (2) were obtained by the reactions of 1,2-(PPh2)2-1,2-C2B10H10 with NiCl2·6H2O or NiBr2·6H2O in CH2Cl2 under the solvothermal condition. Both of the two complexes have been characterized by the elemental analysis, FT-IR, 1H and 13C NMR spectroscopy and single crystal X-ray diffraction. The X-ray structure analysis for these two complexes reveals the
nido-nature of the carborane diphosphine ligand, indicating that the solvothermal synthesis is an efficient method for the degradation
of the closo-carborane diphosphine ligand. |
