Poly[diaqua(₂-1,3-di-4-pyridylpropane-²N:N')(₂-thiophene-2,5-dicarboxylato-²O:O')nickel(II)]: a two-dimensional bilayered coordination polymer

K.-F. Han, D. Wang and Z.-M. Wang

Abstract: The hydrothermally prepared title compound, [Ni(C₆H₂O₄S)(C₁₃H₁₄N₂)(H₂O)₂]_n, is an Ni polymer based on thiophene-2,5-dicarboxylate dianions (tda^2-) and 1,3-di-4-pyridylpropane (bpp) ligands. Each Ni atom is coordinated by two carboxylate O atoms from two independent tda^2- groups along the a direction, two N atoms from two bpp ligands along the b direction, and two aqua O atoms, in a distorted octahedral geometry. This leads to a two-dimensional grid-type bilayer assembly running parallel to the (001) plane, in which the bilayer is formed through intermolecular O-HO hydrogen bonds.
