Abstract:
Adding 4,4′-(phenylazanediyl)dibenzoic acid (H2L) ligand and cadmium(Ⅱ) ions to 1,4-bis-(imidazol-1-yl)benzene (bimb) and 1,4-bis(pyridine-4-ylmethoxy)benzene (bpmb), we synthesized two new types of metal cadmium organicinorganic coordination polymers {[CdL(bimb)0.5]·2H2O}n(1) and [Cd(HL)2(bpmb)0.5]n(2) under the hydrothermal conditions. We determined the structure of the two polymers by means of XRD, and characterized their structures with the help of elemental analysis, IR spectroscopy, TG and powder Xray diffraction(PXRD). The fluorescence properties of two kinds of coordination polymers were tested at room temperature. The experimental results show that coordination polymer 1 crystallizes in the triclinic space group P1, and its framework is a twodimensional layered structure. Coordination polymer 2 crystallizes in the monoclinic space group C2/c, and it’s a threedimensional supramolecular polymer formed by the Hbond of onedimensional zigzag chains.
Key words: 4,4′-(phenylazanediyl)dibenzoic acid, 1,4-bis(imidazol-1-yl)benzene, 1,4-bis(pyridine-4-ylmethoxy)benzene, metalorganic framework
