摘要
以3-苯氧基甲基-4-(4-甲基苯基)-5-(2-吡啶基)-1,2,4-三唑(L)为配体分别合成了2个金属配合物即[Cu2L2Cl4]·2H2O(1)和[Cd3L2(μ2-Cl)6]n·2n CH3CN(2),对其进行了红外、紫外、热重、粉末衍射、元素分析和晶体结构等表征。配合物1和2都属于三斜晶系,空间群都为P1,单晶结构分析表明,在配合物1中,中心铜( Ⅱ)原子具有畸变三角双锥构型[Cu N3Cl2];配合物2是配位聚合物,每个重复单元有3个Cd( Ⅱ)原子和2个不同的Cd( Ⅱ)配位中心,Cd1( Ⅱ)原子具有中心对称的畸变八面体构型Cd Cl4N2,Cd2( Ⅱ)原子具有畸变的八面体构型Cd Cl4N2。
Two complexes [CuzL2C14]·2H20 (1) and [Cd3L2(μ/2Cl)6]n·2nCH3CN (2) were obtained by the reaction of 3-phenoxymethyl-4-(4-methyphenyl)-5-(2-pyridyl)-1,2,4-triazole (L) with Copper(H) chloride and cadmium(I) chloride respectively. The complexes have been characterized by IR, UV, TGA, powder XRD, elemental analyses and crystal structures. The complexes 1 and 2 crystallize in the triclinic space group P1. Crystallographic studies reveal that 1 has a distorted trigonal bipyramidal [CuN3Cl2] coordination. 2 is a polymeric complex, every repeat unit has three cadmium(n) atoms and two different cadmium(n) centers. Cdl(Ⅱ) atom possesses a centrosymmetric distorted-octahedral geometry with [CdCl2Cl'2N2], and Cd2(Ⅱ) atom has a distorted-octahedral geometries with [CdCl2Cl'Cl"NN'].
