摘　　要：本文通过恒温水浴法和溶剂热法分别合成了两种配合物Fe(3PCA)2(H2O)2(1)和[Cu(3PCA)(Im)]n(2)(3PCA=pyrazole-3-carboxylic acid,Im=imidazole),并用X-射线单晶衍射仪测定了它们的晶体结构。结果表明:配合物(1)属于单斜晶系,空间群为P21/c,晶胞参数为:a=5.11446(19),b=11.4930(4),c=9.4084(3),β=95.692(4)°,V=550.30(3)3,Z=2;配合物(2)属于单斜晶系,空间群为P21/c,晶胞参数为:a=11.7198(4),b=8.5094(3),c=8.9703(3),β=111.765(4)°,V=830.82(5)3,Z=4。对配合物(2)进行了磁性质研究,结果表明,铜离子之间存在反铁磁相互作用。In this paper,two complexes,Fe( 3 PCA)2( H2 O)2( 1) and[Cu( 3 PCA)( Im) ]n( 2)( 3 PCA = pyrazole-3-carboxylic acid,Im = imidazole),were synthesized by constant temperature water bath method and solvothermal method respectively. Their crystal structures were determined by X-ray single crystal diffractometer. The results show that the complex( 1) belongs to the monoclinic system,the space group is P21/c,the unit cell parameters are: a = 5. 11446( 19) ,b = 11. 4930( 4) ,c = 9. 4084( 3) ,β = 95. 692( 4) °,V= 550. 30( 3) 3,Z = 2; the complex( 2) belongs to monoclinic system with space group P21/c,the parameters are: a =11. 7198( 4) ,b = 8. 5094( 3) ,c = 8. 9703( 3) ,β = 111. 765( 4) °,V = 830. 82( 5) 3,Z= 4. The magnetic properties of the complex( 2) were studied.The results show that there is an antiferromagnetic interaction between copper ions.
