The title compound, [Ni(C(2)O(4))(C(10)H(8)N(2))](n), is isostructural with its Mn(II), Fe(II), Cu(II) and Zn(II) analogues. Each Ni(II) atom is chelated by two oxalate ligands and one 2,2'-bipyridine, forming a slightly distorted octa-hedral geometry. Oxlate acts as a bridge to link neighbouring pairs of Ni(II) cations, forming a one-dimensional wave-like chain. The crystal showed partial inversion twinning.
