AbstractA novel coordination polymer, [Ag-4(bpdc)(H(2)bpdc)(Hbpdc)(2)](n) (bpdc=2,2'-bipyridyl-3,3'-dicarboxylate), was hydrothermally synthesized at 403 K and structurally characterized by single crystal X-ray diffraction analysis. The compound crystalizes in the monoclinic space group C2/c with a= 1.9516(4) rim, b=1.9503(4) nm, c=1.2566(3) nm, and beta= 112.48(3)degrees. In the two-dimensional crystal structure, Ag-I center is coordinated, in a scarce coordination environment, double-capped tetrahedron, by one bpdc ligand to form N-Ag-N chelate bond via two pyridyl N atoms, and other two bpdc ligands to form two O-Ag-O chelate bonds, respectively, via two carboxyl 0 atoms. The bpdc ligands are present in one non-protonated form, bpdc, and two protonated forms, Hbpdc and H2bpdc, which all act as mu(3)-ligand in a hexadentate fashion (N, N'; 0, O'; 0, O') to coordinate with three Ag centers, respectively, through the three chelate bonds. This coordinated fashion of bpdc ligand is first found in the title compound. UV-Vis-NIR reflectance spectroscopy study revealed insulator nature for the crystal with an optical energy gap of 3.1 eV.
