COA of Formula: C9H10BKN6. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Coordination chemistry of dimethylgold(III) and methylmercury(II). Synthesis, proton NMR and structural studies of poly(pyrazol-1-yl)borate complexes. Author is Canty, Allan J.; Minchin, Nigel J.; Patrick, Jennifer M.; White, Allan H..
Dimethylgold(III) and methylmercury(II) form complexes Me2AuL and MeHgL [L = poly(pyrazol-1-yl)borate ligands, e.g., [HB(pz)3]- and [B(pz)4]-]. The structure of Me2Au[HB(pz)3] was determined by single-crystal x-ray diffraction. This complex has square-planar coordination for the Au atom involving 2 coordinated pyrazole rings and 1 uncoordinated ring, in contrast to the isoelectronic cation [Me2Au[(pz)3CH]]+, which has square-planar coordination with a weak axial Au-N interaction. Variable-temperature 1H NMR in CD2Cl2 indicates a rapid equilibrium between pyrazole-ring environments at ambient temperature and, for the MeHgII complexes, down to -90°. For the Me2AuIII complexes, spectra at -90° indicate pyrazole-ring environments in ratios 2:1 [L = [HB(pz)3]-] and 2:1:1 [L = [B(pz)4]-].
