A Novel 4-Connected Zn(II) Compound With 4,4′–Oxydiphthalic Acid: Synthesis, Structure and Luminescence

A novel Zn(II) coordination polymer, [Zn(H2ODPT)(bpp)]n (1) (H4ODPT = 4,4′–oxydiphthalic acid, bpp = 1,3–bis(4–pyridyl)– propane), was hydrothermally synthesized by the reactions of Zn(II) nitrate, H4ODPT, and bpp. Single crystal X-ray analysis reveals that 1 is a two-dimensional (2D) layer structure. In this 2D layer structure, H4ODPT is half deprotoned into H2ODPT2−. Moreover, the luminescent property of this compound was also investigated in the solid state at room temperature.
