Synthesis,structures and properties of two carboxylate-bridged coordination polymers with linear and ladder chain motifs |

| Abstract: | Two cadmium(II) compounds, [Cd(nip)(phen)2] n (1) and [Cd2(nip)2(phen)2] n (2) [nip = 5-nitroisophthalate, phen = 1,10-phenanthroline], have been synthesized under hydro (or solvo) thermal conditions and characterized by single-crystal X-ray diffraction. Compound 1 exhibits a 1-D linear chain structure adopting the coordination mode in which one Cd is coordinated to two phen ligands. The formation of 1 was favored by selecting Cd(phen)2(NO3)2 as metal source in ethanol-water. Compound 2 displays a 1-D ladder-like chain structure featuring di-cadmium units. Both 1 and 2 are further assembled into 3-D supramolecular frameworks through interchain hydrogen bonding. |
