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.
