Abstract
The crystal structure of the title complex, [Ni(C(7)H(4)NO(4))(2)(C(10)H(8)N(2))(2)](n), exhibits a two-dimensional network, which is built up from slightly distorted NiN(4)O(2) polyhedra (2 symmetry), bipyridine ligands, and carboxyl-ate anions. The Ni(II) atoms are six-coordinated by two O atoms of two monodentate carboxyl-ate anions and four N atoms from bipyridine ligands and are connected into layers by the 4,4'-bipyridine ligands.
