Each NiII atom is chelated by two oxalate ligands and one 2,2¡ä-bipyridine, forming a slightly distorted octahedral geometry. Oxlate acts as a bridge to link neighbouring pairs of NiII cations, forming a one-dimensional wave-like chain. The crystal showed partial inversion twinning. %U http://scripts.iucr.org/cgi-bin/paper?S1600536808028389
