Two novel coordination polymers,[Zn(ImNIPA)(DMSO)]n (1) and [Cd(ImNIPA)-(DMSO)]n (2) (H2ImNIPA =5-(6-(1H-imidazol-l-yl)-1,3-dioxo-1H-benzo[de]iso-quinolin-2(3H)-yl)isophthalic acid,DMSO =dimethylsulfoxide),were prepared under solvothermal conditions through the reactions of Zn2+/Cd2+ and a new imidazole-containing isophthalic ligand H2ImNIPA.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 ImNIPA2-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.
