1-D and 2-D lanthanide coordination polymers constructed from 4-sulfobenzoate and 1,10-phenanthroline

Two complexes {[Dy-2(4-SBA)(3)(phen)(2)(H2O)(4)]center dot 2H(2)O}(n) (1) and {[Eu-2(4-SBA)(3)(phen)(2)( H2O)(2)]}(n). (2) (4SBA = 4-sulfobenzoate, phen = 11,11 0-phenanthroline) were synthesized and their structures were determined by X-ray crystallography. The I has a 1-D chain structure by bidentate and tridentate 4-SBA ligands as linkages and 3-1) network was formed by strong hydrogen bonds. The 2 has a 2-D network structure by tridentate and tetradentate 4-SBA ligands as linkages. The luminescence properties and thermal stability of the two complexes were investigated.
