A New 1D Cadmium Coordination Polymer Based on N- and O-donor Ligands： Synthesis, Structure and Luminescent property

摘要

One new cadmium coordination polymer, [Cd（nbdc）（dmpy）]n （1, H2nbdc = 2-nitro- terephthalic acid, dmpy = 5,5′-dimethyl-2,2′-bipyridine） has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis （TGA）, and single-crystal X-ray diffraction. Complex 1 is of monoclinic system, space group C2/c with a = 11.7684（9）, b = 24.3715（19）, c = 13.9898（11） , β = 107.652（2）°, V = 3823.5（5） 3, C20H15N3O6Cd, Z = 8, Mr = 505.75, Dc = 1.757 g/cm3, μ（MoKα） = 1.187 mm-1, F（000） = 2016, the final R = 0.0207 and wR = 0.0560 for 3034 observed reflections with I 〉 2σ（I）. 1 exhibits an interesting one-dimensional double chain structure. Furthermore, the luminescent property of 1 has also been investigated.
