摘要: 本文合成了一个复杂的单核配合物 [Co(H2dmg)2Cl2]3·[Co(H2dmg)2Cl(OH)]·[Co(Hdmg)(phen)]·(H2O)4 (H2dmg=dimethylglyoxime, phen=1,10-Phenanthroline).通过X射线衍射技术获得其单晶结构.在单晶结构中,每五个单核钴(II)的配位结构形成一个重复单元,是一个较为复杂的单晶.其空间群为P-1,晶胞参数为a=1.3738nm;b=1.4396nm;c=1.8656nm.本文中我们将讨论该化合物的分子结构及相关光谱性质.

Abstract: A new assemble crystal[Co(H2dmg)2Cl2]3·[Co(H2dmg)2Cl(OH)]·[Co(Hdmg)(phen)]·(H2O)4 (H2dmg=dimethylglyoxime, phen=1,10-Phenanthroline) was synthesized and its structure was determined by X-ray diffraction method. The five central Co2+ ions and relevant ligands form a unit which piles up in space.The space group is P-1,cell parameters a=1.3738nm,b=1.4396nm,c=1.8656nm. Molecular structure and spectroscopic properties of the complex were also discussed in this article.
