摘　　要：蝎合配体氢三 (3 -对甲氧基苯基吡唑 -1 )硼酸钾 KTp An及氢三 (3 -对甲氧基苯基 ,5-甲基吡唑 -1 )硼酸钾KTp An,Me与 B族金属盐 MX2 (M=Zn,Cd;X=Cl,OAc)反应 ,得到一系列新的蝎合物 .对这些蝎合物进行了元素分析、红外光谱、核磁共振谱的测定与研究 .对 Tp An Zn Cl(1 a)的 X射线晶体结构分析表明 ,它属于P2 1/n空间群 ,晶胞参数 :a=1 .0 0 55(2 ) nm,b=1 .6890 (3 ) nm,c=1 .7760 (4 ) nm,β =1 0 2 .1 6(3 )°,Z=4 ,最终的偏离因子 R=0 .0 50 0 ,w R=0 .1 2 0 2 .Two scorpionate ligands KTp An and KTp An were prepared and reacted with MX 2(M=Zn, Cd; X=Cl, OAc) affording some new complexes, which were characterized by elemental analysis, IR and \{ 1H NMR\}. The single crystal structure of Tp An ZnCl has been determined by a four circle X ray diffractometer, which shows that the coordination environment about the Zn center is distorted tetrahedral. The crystals are monoclinic, space group P2 1/n , with dimensions a= 1.00 5 5(2) nm, b = 1.689 0(3) nm, c = 1.776 0(4) nm, β =102.16(3)° and Z=4, with final residuals R = 0.050 0 and wR = 0.120 2.
