中文摘要：
以Co（dien）2·Cl3为模板剂,在水热条件下导向合成出新型草酸盐化合物[Co（dien）2]·[NaCo2（C2O4）4]·H2O,并通过X射线单晶结构分析、元素分析、ICP以及X射线粉末衍射分析对该化合物的结构进行了表征.结果表明,该化合物结构属于单斜晶系,C2/c空间群,晶胞参数a=1.3805（3）nm,b=1.3017（3）nm,c=1.5913（3）nm,β=104.41（3）°,V=2.7695（10）nm^3,Z=4.在该化合物的结构中,Co^2＋先与草酸基团相互交替连接形成一个常见的链状结构基元[Co（C2O4）2]n^2n-,这些链状结构基元进一步被分布于链间的Na^＋连接成三维开放骨架结构[NaCo2（C2O4）4]n^3n-.金属配合物离子Co（dien）2^3＋存在于孔道中起模板剂的作用.
英文摘要：
Using Co（dien）2·Cl3 as the template,a new oxalate compound,[Co（dien）2]·[NaCo2（C2O4）4],was synthesized under hydrothermal condition.Its structure was determined by single-crystal X-ray diffraction analysis,elemental analyses,ICP and X-ray powder diffraction.It crystallizes in monoclinic system space group C2/c with a=1.3805（3） nm,b=1.3017（3） nm,c=1.5913（3） nm,β=104.41（3）°,V=2.7695（10） nm^3,Z=8.In this structure,the Co^2＋ ions first link to oxalate ligands to form a chain-like building unit[Co（C2O4）2]n^2n-,then those chain-like building units are further connected by Na＋ cations,which are dispersed between the chains,to form a three dimensional oxalate open-framework of [NaCo2（C2O4）4]n^3n-.The complex cations Co（dien）2^3＋ are encapsulated inside the channels as template.
