HYDROTRIS(PYRAZOLYL)BORATE MOLYBDENUM CHEMISTRY - SPIN TRIPLET 16-ELECTRON CARBONYL DERIVATIVES OF MOLYBDENUM(II), AND THE X-RAY STRUCTURE OF THE MO(V) OXO COMPOUND (HB(3,5-ME(2)C(3)N(2)H)(3))MOOI2

摘要

The hydrotris(3, 5-dimethylpyrazolyl) borate complexes Tp*Mo(CO)(2)X (X = Cl, I) are rare examples of 16-electron carbonyl derivatives with a spin tripler ground state, which exhibit relatively sharp contact-shifted H-1 NMR spectra. Oxidation of Tp*MoI(CO)(2) led to the isolation and crystallographic characterization of Tp*MoOI2. Copyright 1997 Elsevier Science Ltd. [References: 34]
