摘　　要：通过水热法合成2个新型配合物:[Er_4(HL)_4(L)_4·(H_2O)_(20)](配合物1)和[Eu_2(HL)_2(L)_2·(H_2O)_(10)](配合物2),[H_2L=4′-(5-四氮唑基)-联苯4-甲酸].利用红外光谱、元素分析和X-射线单晶衍射等对其结构进行表征.X-射线单晶衍射分析结果:2个配合物均属于三斜晶系,P-1空间群.配合物1:a=1.204 6(2)nm,b=1.611 3(3)nm,c=1.713 7(3)nm,α=83.48(3)°,β=70.39(3)°,γ=68.57(3)°,Z=1;配合物2:a=0.80900(16)nm,b=1.1810(2)nm,c=1.727 0(3)nm,α=105.23(3)°,β=96.69(3)°,γ=107.92(3)°,Z=1.配合物1和配合物2均为零维结构,通过氢键作用形成三维网状结构.Two new complexes,[Er_4(HL)_4(L)_4-(H_2O)_(20)](1) and[Eu_2(HL)_2(L)_2-(H_2O)_(10)](2)were prepared through hydrothermal reaction,(H_2L =4'-(5-tetrazole-yl)-biphenyl-4-carboxylic acid).Their structure were characterized by IR,elemental analysis and X-ray single crystal diffraction,etc.The single-crystal X-ray diffraction analysis showed that two compounds belong to triclinic system,P-1 space group.In complex 1,a = 1.204 6(2) nm,b = 1.611 3(3) nm,c = 1.713 7(3) nm,a =83.48(3)°,β=70.39(3)°,γ=68.57(3)°,Z = l.In complex 2,a =0.809 00(16)nm,b= 1.181 0(2)nm,c = 1.727 0(3)nm,α= 105.23(3)°,β=96.69(3)°,γ = 107.92(3)°,Z = l.Two complexes are zero-dimensional structure,which are further extended three-dimensional network structures through hydrogen bonding.
