A 1D linear chain coordination polymer constructed by Cu(II) with H3Tci and Bipy ligands (H3Tci = tris(2-carboxyethyl)isocyanurate, Bipy = 4,4′-bipyridine)

A new coordination polymer [Cu(H2Tci)2(Bipy)(H2O)] · 2H2O (I) (H3Tci = tris(2-carboxyethyl)isocyanurate, Bipy = 4,4′-bipyridine) has been synthesized and characterized by elemental analysis, IR, and X-ray single-crystal diffraction. The X-ray diffraction analysis reveals that I (C34H42CuN8O21) crystallizes in the monoclinic crystal system, space group P21/c. In I, the metal centers are linked by Bipy ligands to generate an infinite linear chain and the H2Tci ligands adopt monodentate coordination mode to graft the linear chain. The adjacent chains are linked by hydrogen bonds to form a three-dimensional supramolecular framework.
