利用水热法合成了2个新的对咪唑基苯甲酸镉配合物Cd(C10N2O2H7)2·H2O(1)和Cd2(H2O)5(C10N2O2H7)(C9O6H3)·4H2O(2),通过元素分析、红外光谱和X-射线单晶衍射进行了表征.结果表明:化合物1属于正交晶系,Pnna空间群,a=1.389 5(5)nm,b=1.665 4(5)nm,c=0.828 2(5)nm,V=1.916 5(15)nm3,Z=4,R1=0.026 3,wR2=0.0793;化合物2属于单斜晶系,P21/c空间群,晶胞参数a=1.370 2nm,b=1.751 1nm,c=1.255 7(4)nm,β=114.819(6)°,V=2.734 6(14)nm3,Z=4,R1=0.057 3,wR2=0.166 7.

Two novel Cd（ Ⅱ ） complexes constructed by HL, [Cd（L）（C2O4）0.5 （H2O）]n（HL=4-（imid- azol-l-yl） benzoic acid）, have been synthesized under hydrothermal conditions and characterized by ele- mental analyses, IR spectrum and single crystal X-ray diffraction. The complex 1 crystallizes in the orthorhombic system, space group Pnna, a=1. 389 5（5） nm,b=1. 665 4（5） nm,c=0. 828 2（5） nm, V=1. 916 5（15） nm3 ,Z=4,R1 =0. 026 3,wR2 =0. 079 3. The complex 2 is crystallized in the mono- clinic system, space group P21/c, a= 1.370 2（4） nm,b= 1. 751 1（5） nm,c=1.255 7（4） nm,fl= 114. 819（6）°,V=2. 734 6（14）nm3 ,Z = 4,R1 = 0. 057 3,wR2 = 0. 166 7. Both the titled two comple- xes include a grid-like 2D layer.
