catena-Poly[[diaqua(2,2'-bipyridine-²N,N')nickel(II)]--biphenyl-2,2'-dicarboxylato-²O:O']

Z. An and X.-C. Niu

Abstract: In the title compound, [Ni(C₁₄H₈O₄)(C₁₀H₈N₂)(H₂O)₂]_n, the Ni^II atom is coordinated in a slightly distorted octahedral geometry by two water molecules, two N atoms from a 2,2'-bipyridine ligand and two O atoms from the carboxylate groups of two 2,2'-biphenyldicarboxylate (2,2'-dpa) ligands. The 2,2'-dpa ligand acts as a bridge between neighbouring Ni^II atoms, forming one-dimensional coordination polymers along [100]. The coordinated water molecules form hydrogen bonds to the carboxylate O atoms of 2,2'-dpa within the same coordination polymer, and one O-H interaction is also formed to 2,2'-dpa.
