摘　　要：利用配体1-(4-羟基苯)-5-巯基四氮唑(H2L)和金属盐酸盐在水溶液中反应,合成了4种离子型化合物,并测定了它们的晶体结构。分析结果显示它们是异质同晶,都属于P1空间群,分子通式为[M(H2O)6](HL)2[M=MnⅡ(1),CoⅡ(2),NiⅡ(3),ZnⅡ(4)]。在这些化合物中,中心金属原子都采取六配位模式,形成一个近乎理想的八面体构型。晶体中通过氢键(M-OH2…O-C)和偏移面π-π堆积作用形成独特的三维超分子网络结构。The reactions of several divalent transition metals with 1-（4-Hydroxyphenyl）-5-thioacetatetetrazole （H2L） were studied in aqueous solution. Mn^Ⅱ, Co^Ⅱ, Ni^Ⅱ, and Zn^Ⅱ produced ionic products of general formula [M（H2O）6]（HL）2. The four compounds were characterized by crystallographic methods. And the results have shown that their crystals are isostructural and belong to the triclinic P1 space group. The metal center in each compound is six-coordinated, forming an ideal octahedral geometry. These neutral formula units make unique three-dimensional supramolecular architectures through hydrogen bonding （M-OH2…O-C） and offset-panel π-π stacking interactions and stabilized by electrostatic force.
