| Abstract: Reactions of tridentate mononuclear hydrotris (3,5-dimethyl-1-pyrazolyl) borate molybdenum(Ⅴ) complex Tp*Mo(O)Cl2 (1)(Tp*=hydrido-tris 3,5-dimethyl-1-pyrazolyl-borate, HB(C3H(Me2)N2)3) with dilithium dichalcogenolate carboranes [(THF)2LiE2C2B10H10(THF)]2 [E=S(2a)，Se(2b)，Te(2c)] afforded mononuclear complexes Tp*Mo(O)E2C2B10H10 [E=S(3a)，Se(3b)，Te(3c)] in moderate yields. Complexes 3a～3c have been characterized by IR and elemental analysis. The molecular structure of 3b was determined by X-ray crystallographic analysis. In the air 3a can convert into a novel binuclear oxo molybdenum complex [HMe2Pz][Tp*Mo(O)( μ2-O)2Mo(O)S2C2B10H10] 4a. The molecular geometry of 4a has been determined by a single crystal X-ray structure analysis. According to the short Mo-Mo distance (0.254 83(12) nm), direct metal-metal interaction exists. CCDC: 263618, 3b; 263619, 4a. |
