The cobalt(II) complex C20H34O20Co has been synthesized and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. The crystal belongs to triclinic, space group P with a = 5.1374(10), b = 10.519(2), c = 12.913(3) (A), α = 86.89(3), β = 79.94(3), γ = 86.74(3)o, V = 685.3(3) (A)3, Z = 1, Mr = 653.40, Dc = 1.583 g/cm3, μ = 0.717 mm-1, F(000) = 341, the final R = 0.0657 and wR = 0.1141 for 1900 observed reflections with I > 2σ(I). The cobalt ion is six-coordinated by two O atoms of different 1,3-bdoaH- ligands and four water molecules, residing in an octahedral environment. The intermolecular hydrogen bonds form a 3-D supramolecular network structure.
