Three New Coordination Polymers Constructed from Mixed Ligands: Syntheses, Luminescence and Magnetism

Three new coordination polymers, namely, {[Cd(H(2)bptc)(IP)(H2O)]center dot 2H(2)O} (n) (1), {[Mn-2(IP)(2)(dstc)]center dot 6H(2)O} (n) (2) and {[Zn-2(IP)(2)(dstc)]center dot 3H(2)O} (n) (3) (IP = 1H-imidazo[4,5-f][1,10]-phenanthroline, H(4)bptc = 3,3',4,4'-benzophenonetetracarboxylic acid, and H(4)dstc = 3,3',4,4'-diphenylsulfonetetracarboxylic acid) have rationally designed and characterized by single crystal X-ray diffraction. Polymer 1 shows a 1D ribbon-like structure. Although compounds 2 and 3 feature 2D grid networks, the coordinative modes of dstc ligand and the arrangements of IP ligand are very different. Furthermore, the luminescence properties for 1 and 3, as well as the magnetism of 2 are explored in detail.
