文摘

A novel copper(II) inorganic-organic hybrid compound [CuL(DMF)(CH₃OH)]₂(PMo^VMo^VI₁₁O₄₀)¡¤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 N₃O₂ donor set. In solid-state there are three types of CH?¦Ð interactions between adjacent [CuL(DMF)(CH₃OH)]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.
