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 P21/n with a = 12.936（5）, b = 15.245（5）, c = 13.499（5） ？, β = 105.456（5）o, V = 2565.9（16） A^3, Z = 4, C（31）H（16）CdClFN4O4, Mr = 675.33, Dc = 1.748 g/cm^3, F（000） = 1344, μ（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···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.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）.
