Abstract: The title compound, [Ni(C₂O₄)(C₁₀H₈N₂)]_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 octahedral 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.
