The compound [RuClH(bpzm)(cod)][bpzm = bis(pyrazol-1-yl)methane] reacts with KHB(pz)3 to give [RuHB(pz)3}H(cod)] as the only ruthenium product. Nuclear Overhauser enhancement (NOE) measurements have been used as a valuable method for the assignment of the H3 and H5 resonances of the pyrazolyl groups. Heteronuclear 1H–13C correlation (COSY) experiments have been recorded to determine the assignment of
