N2 - A neoteric organic-inorganic hybrid Co-substituted phosphotungstate H6{[Co(en)2(OAc)2]2[Co4(H2O)2(PW9O34)2]}∙2H2en∙36H2O (1, en = enthylenediamine) has been made under hydrothermal conditions and characterized by IR spectrum, thermogravimetric analysis, diffuse-reflectance spectroscopy, powder X-ray diffraction, single-crystal X-ray diffraction and cyclic voltammetry, respectively. Crystal data for 1: monoclinic, P21/c, a = 18.2234(12), b = 15.3696(9), c = 20.1706(17) Å, β = 106.563(8)°, V = 5415.1(7) Å3, Z = 2, Mr = 6072.30, Dc = 3.724 g/cm3, μ = 20.087 mm-1, F(000) = 5540, R = 0.0585, wR = 0.1543 and S = 1.024. Single-crystal X-ray structure analysis reveals that compound 1 exhibits a 3-D supramolecular framework via H-bonding interactions, in which the discrete Co-complex is modified by two types of organic ligands, en and acetate. In addition, the adsorption experiments demonstrate compound 1 possesses a remarkable capability for scavenging of methylene blue.
