dc.description.abstractFifteen complexes derived from dihydrobispyrazolylborates and molybdenum have been studied by 1H, 13C and 15N NMR spectroscopy both in solution (1H and 13C in CDCl 3) and in the solid state (13C and 19N). The Mo bears two CO and one methallyl molecules. In one case, compound 15, the pyrazoles are actually 2H-indazoles. Besides the fluxional behavior of all the complexes, problems related to the positional isomerism (different substituents at positions 3 and 5 in the pyrazole ring) are observed. In 1H NMR it was noted the diastereotopy of the BH2 protons, one of them forming an agostic bond B-H-Mo, being strongly shielded (1JBH ∼ 90 Hz). The 13C chemical shifts are linearly correlated to those of the corresponding NH-pyrazoles.-
