| Abstract: | Two novel cadmium(II) coordination polymers Cd(pyip)(ox)]·H2O (1) and Cd2(pyip)2(ox)2·(H2O)]Cd(pyip)(ox)]·4(H2O) (2) (pyip = 2-(pyridin-3-yl-1H-imidazo 4,5-f]1,10]phenanthroline, H2ox = oxalic acid), have been hydrothermal synthesized and characterized by single crystal X-ray diffraction. Compound 1 is 1D zigzag chain, in which oxalate anion as bridging ligand is responsible for the formation of the main framework and pyip as chelating ligand grafts on two sides of the zigzag chain. Compound 2 contains two kinds of independent polymers Cd2(pyip)2(ox)2(H2O)] (A) and Cd(pyip)(ox)] (B) to form an interdigitated 1D + 1D structure, in which polymers A and B are paratactically assembled in an ABCD sequence. The fundamental unit of polymer B in 2 is the same as that in 1. For compounds 1-2, weak interactions, primarily hydrogen bonding and π?π stacking interactions, have greatly influence on the supramolecular motifs recognized in the crystal packing. Especially, the oxalate anions as bridging ligand simultaneously adopt multiform coordination modes in two compounds. In addition, 1 and 2 displayed a strong fluorescent emission in the solid state at room temperature. |
