Two novel cadmium(II) coordination polymers based on bis-functionalized ligand 4 '-(4-carboxyphenyl)-2, 2 ':6 ', 2 ''-terpyridine

Two novel cadmium(II) coordination polymers [Cd(cptpy)(2)](n)center dot nH(2)O (1) with a 1D double chain structure and [Cd-2(cptpy)(2)(ox)](n)center dot 2.5nH(2)O (2) with an interesting 3-connected uninodal six-fold interpenetrating ths network (Hcptpy=4'-(4-carboxyphenyl)-2,2':6',2 ''-terpyridine, H(2)ox = oxalic acid) have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, single crystal X-ray diffraction and fluorescence spectra.
