摘要： 合成了锌(Ⅱ)与2,2'-联吡啶胺(dpa)和3-苯丙酸(HPPr)混配配合物[Zn(dpa)(PPr)2]·2H2O,并测定其晶体结构.晶体属三斜晶系,P1空间群,晶胞参数a＝10.541(1)nm,b=11.333(1)nm,c=11.698(1)nm,α=91.00(1)°,β=90.96(1)°,γ=88.38(1)°,Z=2,2个PPr-1羧基上的4个氧原子、1个dpa上的2个氮原子分别与中心离子Zn(Ⅱ)配位,构型为畸变八面体.2个结晶水与配体间可能存在着分子内氢键.通过元素分析、IR、摩尔电导和热重分析表征了配合物的结构.

Abstract: The zinc(Ⅱ) complex [Zn(dpa)(PPr)2]·2H2O was prepared and its crystal structure was determined. The crystal belongs to triclinic, space group P1,with the crystal cell parameters: a=10.541(1) nm, b=11.333(1) nm, c=11.698(1) nm, α=91.00(1)°, β=90.96(1)°, γ=88.38(1)°, Z=2. Four carboxyl oxygen atoms from two PPr- and two nitrogen atoms from dpa coordinate with Zn(Ⅱ) respectively to form a distorted octahedral. Intramolecular hydrogen bonds were observed involving two water molecules and the coordinated atoms. The complex was characterized by elementary analyses, IR, molar conductance and differential thermal analyses.

Key words: Zinic complex, Crystal structure, Characterization
