摘要：
Two novel coordination polymers, [Zn(;NIPA)（DMSO）];（1） and [Cd(;NIPA)-（DMSO）];（2）(H;NIPA = 5-(6-（1 H-imidazol-1-yl）-1,3-dioxo-1 H-benzo[de]iso-quinolin-2（3H）-yl)isophthalic acid, DMSO = dimethylsulfoxide), were prepared under solvothermal conditions through the reactions of Zn;/Cd;and a new imidazole-containing isophthalic ligand H;ImNIPA. The compounds were fully characterized by elemental analysis, FT-IR spectroscopy, powder X-ray diffraction analysis and X-ray single-crystal diffraction analysis. Both 1 and 2 are two-dimensional（2D） coordination layers via the combination of 3-connected metal nodes and;NIPA;linker, featuring（6, 3） honeycomb-type topology. In addition, the 2D layers in the two compounds are further extended into 3D supramolecular frameworks via π-π stacking interactions. Finally, the thermal-stability and solid-state luminescence properties of them were also investigated.
