【摘要】 4-甲基-3-苯基-5-(2-吡啶基)-1,2,4-三唑(L)分别与CuCl2·2H2O、Ni(NO3)2·6H2O、Cu(ClO4)2·6H2O和Cd(NO3)2·4H2O反应合成了配合物[CuL2Cl]Cl·H2O(1)、[NiL2(H2O)2](NO3)2(2)、[CuL2(H2O)2](ClO4)2(3)和[CdL2(NO3)2]·CH3CN(4),测定了它们的X射线单晶结构,并用红外光谱、紫外光谱、荧光和热重分析进行了表征。配合物1属于正交晶系,空间群为Fddd,中心离子Cu1(Ⅱ)具有畸变的四方锥构型[CuN4Cl]。配合物2、3和4都属于单斜晶系,空间群分别为P21/n,P21/n和P21/c。配合物2、3和4的中心离子Ni1(Ⅱ)、Cu1(Ⅱ)和Cd1(Ⅱ)都为畸变的八面体构型[NiN4O2]、[CuN4O2]和[CdN4O2]。
【Abstract】 Complexes of[CuL2Cl]Cl·H2O(1),[NiL2(H2O)2](NO3)2(2),[CuL2(H2O)2](ClO4)2(3)and[CdL2(NO3)2]·CH3CN(4)were synthesized by the reactions of 4-methyl-3-phenyl-5-(2-pyridyl)-1,2,4-triazole(L)with CuCl2·2H2O,Ni(NO3)2·6H2O,Cu(ClO4)2·6H2O and Cd(NO3)2·4H2O,respectively.Their structures were determined by single crystal X-ray diffraction,and characterized by IR,UV-Vis,fluorescence and TGA.Complex 1 belongs to orthorhombic system with space group Fddd,and the central Cu1(Ⅱ)ion has a distorted tetragonal pyramid geometry[CuN4Cl].The complexes of 2,3 and 4 all belong to monoclinic system with space groups P21/n,P21/n and P21/c,respectively.All the central metal ions of 2,3 and 4 have distorted octahedral configuration[NiN4O2],[CuN4O2],[CdN4O2].
