摘要
将醋酸钴、硝酸钠与联苯二甲酸和邻菲咯啉反应,得到化合物[Co_3(DPA)_3 (PHEN)_6]·CH_3OH·H_2O(H_2DPA=diphenic acid;PHEN=1,10-phenanthroline).通过单晶X射线衍射对其结构进行了确证.结构分析表明:配合物的三个Co(Ⅱ)都是六配位的八面体结构,分子间通过静电引力、氢键使得化合物构成三维晶体堆积图.变温磁化曲线的测试表明:该配合物存在弱的反铁磁性。
A Cobalt complex, [Co3(DPA)3(PHEN)6]·CH3OH·H2O(H2DPA = diphenic acid; PHEN = 1,10 - phenanthroline) , is synthesized and characterized by EA, X - ray single -crystal diffraction and magnetism. X - ray single crystal diffraction reveals that the Co( Ⅱ ) atom is coordinated in a distorted octahedron model. Both the classic and the non - classic hydrogen - bonding interactions extend the complex to generate a 3D structure. The magnetic properties of it confirm the presence of antiferromagnetic behavior.
