Resumo

Thienylmercury(II) polypyrazolylborates (Tp∗ = hydridotris-(3,5-dimethylpyrazol-1-yl)borato, TpMe = hydridotris(3-methylpyrazol-lyl)borato, pzTp = tetrakis(pyrazol-I-yl)borato) have been synthesised and characterised through elemental analysis, electrical conductivity, molecular weights, and spectral measurements (IR in the solid state and 1H, 13C, 199Hg NMR in solution). The structure of [(5-Me)Thien-2-yl]Hg-(ν-Pz)2B(Pz)2 has been determined (Pbcn; a = 22.530(6), b = 9.366(4), c = 19.310(5) Å; Z = 8; R = 0.054). The mercury(II) atom is tricoordinated in an approximately planar “T-shaped” configuration.
