In the title compound, [Co(C10H8N2)3](PF6)2, the CoII atom is coordinated by the six N atoms of three 2,2'-bipyridyl ligands and adopts a highly distorted octahedral geometry. The crystal used was a merohedral twin, the refined ratio of twin components being 0.820 (1):0.180 (1). The crystal structure features weak C-HF interactions, forming a three-dimensional network.
