摘要： 以Co(dien)2?Cl3为模板剂，在水热条件下导向合成出一例新型草酸盐化合物[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标征. 结果表明，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) nm3，Z = 4. 在这个结构中，二价Co2+离子先与草酸基团相互交替连接形成一个常见链状结构基元[Co(C2O4)2]n2n-，这些链状结构基元进一步被散布于链间的Na+离子连接成三维草酸盐开放骨架结构[NaCo2(C2O4)4]n3n-. 金属配合物离子Co(dien)23+存在于孔道中扮演模板剂的作用.

Abstract: By using Co(dien)2?Cl3 as the template, a novel oxalate compound [Co(dien)2][NaCo2(C2O4)4]?H2O has been synthesized under hydrothermal conditional. Its structure is determined by single-crystal X-ray diffraction analysis, elemental analyses, ICP, and X-ray powder diffraction. It crystallizes in monoclinic, 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) nm3, Z = 8. In this structure, the Co2+ cations are first linked to oxalate ligands to form a familiar chain-like building unit [Co(C2O4)2]n2n-, and then those chain-like building units are further connected by Na+ cations, which are dispersed between the chains, to construct a three dimensional oxalate open-framework of [NaCo2(C2O4)4]n3n-. The complex cations Co(dien)23+ are encapsulated inside the channels as template.
