Abstract

Under the conditions of solvothermal synthesis, a new metal-organic coordination polymer of the composition Cd[H2L] (I, H4L = 4,4'-([2,2'-bipyridine]-6,6'-diylbis(oxy))diphthalic acid). According to X-ray diffraction analysis, each Cd(II) cation binds four organic ligands: one via the coordination of the chelate bipyridyl fragment, two via the bidentate coordination of deprotonated COO groups, and one more via the monodentate coordination of the protonated carboxylate group. The obtained three-dimensional metal-organic framework does not contain free space capable of including guest molecules. Compound I was characterized by powder X-ray diffraction, IR spectroscopy, elemental (C, H, N) and thermogravimetric analyses, and luminescence spectra were recorded for it.
