catena-Poly[[(2,2'-bipyridine)-nickel(II)]-μ-2,4'-oxydibenzoato].

In the title compound, [Ni(C(14)H(8)O(5))(C(10)H(8)N(2))](n), the Ni(II) atom is six-coordinated in a slightly distorted octa-hedral geometry by four O atoms from two chelating carboxyl-ate groups of symmetry-related 2,4'-oxydibenzoate anions and by two N atoms from a 2,2'-bipyridine ligand. The Ni(II) atoms are bridged by the 2,4'-oxydibenzoate anions, resulting in the formation of helical chains parallel to [010] with a repeating unit of 15.039†(2)†à .
