A New (4,8)-Connected scu-Type Heterometallic-Organic Framework: Synthesis, Structure and Luminescent Property

摘要

Presented here is a new heterometallic coordination polymer, namely [ZnCa(btec)(H2O)(2)](n) (1 H(4)btec = 1,2,4,5-benzenetetracarboxylic acid), which was successfully synthesized via the hydrothermal reactions of H(4)btec, Zn(NO3)(2) and CaCl2. Single crystal X-ray structural analysis reveals that compound 1 features a 3D inorganic-organic hybrid framework, which can be simplified into a (4,8)-connected scu topological network by viewing Zn(II) ions, Ca(II) ions, btec(4-) ligands as 4-, 4-, and 8-connected nodes, respectively. Moreover, the luminescent properties of compound 1 and the desolvated samples were also investigated at room temperature.
