| Abstract: | In the study,a novel cobalt oxalate compound,[Co（ C2O4）0. 5（ H2O） ]n（ 1） was synthesized. X-ray single crystal diffraction analysis results showed that the compound belongs to monoclinic,C2 /c space group with the cell parameters a = 1. 1785（ 6） nm,b = 0. 5425（ 3） nm,c = 0. 9665（ 5） nm,β = 126. 371（ 5） °,Z = 8. Each Co2 ＋cations was coordinated with four oxygen atoms from two oxalates and two oxygen atoms from two water molecules. The Co2 ＋cations and oxalate anions were alternately connected to form a 1D chain structure in the b axis direction,between which a 3D supramolecular compound was formed through hydrogen bond. |
