  摘要：

  The interaction between bis(4-methylpyrazol-1-yl)methane or bis(3,4,5-trimethylpyrazol-1-yl)methane and several MX2 salts (M = Mn, Fe, Co, Ni or Cu; X = Cl; M = Mn, Co, Ni or Cu, X = NO3; M = Zn, X = Br) gives 1:1 and 2:1 adducts depending on counter-ion, molar ratio of reagents and solvent of reaction employed. Structural conclusions are drawn from IR, far-IR, UV, magnetic susceptibility and conductivity data. In the crystal structure of the title compound the zinc atom is found in a strongly distorted tetrahedral coordination [N-Zn-N: 92.2(6); Br-Zn-Br: 119.1(1)degrees]. The Zn-N [2.075(19) and 2.078(15) Angstrom] and Zn-Br [2.350(3) and 2.372(3) Angstrom] bond distances are longer than those reported for related compounds owing to steric hindrance of the N-2-donor.
