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

Three new coordination polymers, namely, {[Cd(H2bptc)(IP)(H2O)]·2H2O}n (1), {[Mn2(IP)2(dstc)]·6H2O}n (2) and {[Zn2(IP)2(dstc)]·3H2O}n (3) (IP = 1H-imidazo[4,5-f][1,10]-phenanthroline, H4bptc = 3,3′,4,4′-benzophenonetetracarboxylic acid, and H4dstc = 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.
