A new cobalt (Ⅱ) complex, [ Co (bpdc) ( H2O) 2 ] n ( bpdc = 2,2' - bipyridyl - 3, 3' - dicarboxylato), has been synthesized and its structure determined by X-ray diffraction. The crystal structure of complex belong to Monoclinic system, space group C2/c with a=11.676(3)A,b=8.070(2)A,c=13.028(4)A,α=γ=90°,β=100.303(3)°;Z=4,D=1.854mg/m^3,V=1207.8(6)A^3;[I〉2σ(I)]. In the complex, each Co^2+ is octahedrally coordinated by two chelating pyridyl N atoms from one ligand (bpdc) , two chelating carboxyl O atoms from different carboxylate groups of another ligand (bpdc) , and two coordination water molecules. The pbde as a bridge ligand links two cobalt (Ⅱ) centers to form one-dimensional chain, and via hydrogen bonds to structure two- dimensional reticulation.
