title: Assembly of one novel polyoxometalate-based inorganic-organic compound from copper-Schiff base building block: synthesis, crystal structure and spectral properties.
abstract: A novel copper(II) inorganic-organic hybrid compound [CuL(DMF)(CH(3)OH)](2)(PMo(V)Mo(VI)(11)O(40))·2DMF (L=phenyl 2-pyridyl ketone azine) 1 has been synthesized and characterized by IR, UV, elemental analysis and X-ray crystallography. Cu(II) atom has a distorted square pyramidal environment interconnecting with N(3)O(2) donor set. In solid-state there are three types of C-H···π interactions between adjacent [CuL(DMF)(CH(3)OH)](2+), which generate a two-dimensional (2D) layer. Adjacent 2D layers form porous channels in which polyoxoanions as templates are filled. Simultaneously, the oxygen atoms of polyoxoanion as electron acceptors feather multiple intermolecular hydrogen bonds, through which giving rise to a 3D supramolecular network. The luminescent properties of the compound 1 were investigated in the solid state and in aqueous solution at room temperature, respectively.
