摘要

In this work, we synthesized a new two-dimensional Cd(II) coordination polymer, [Cd(1,4-NDC)(L)] (1), by using mixed 1,4-naphthalenedicarboxylic acid (1,4-H2NDC) and typical chelating N-donor ligands 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline ligand (L). Compound 1 crystallizes in monoclinic, space group P2(1)/n with a = 12.936(5), b = 15.245(5), c = 13.499(5) angstrom, beta = 105.456(5)degrees, V = 2565.9(16) angstrom(3), Z = 4, C31H16CdClFN4O4, M-r = 675.33, D-c = 1.748 g/cm(3), F(000) = 1344, mu(MoKa) = 1.011 mm(-1), R = 0.0350 and wR = 0.0926. In 1, each 1,4-NDC anion bridges three adjacent Cd(II) atoms to give a two-dimensional layer structure. The L ligands are attached on both sides of the layer in chelating coordination modes. In addition, the N-H center dot center dot center dot O hydrogen bond between L and 1,4-NDC further stabilizes the layer structure of 1. Moreover, the solid state luminescent property of 1 was also investigated at room temperature.
