Abstract: The title complex, [Co(C₁₅H₁₁N₃)₂](C₄N₃)₂, is built up from discrete [Co(terpy)₂]²⁺ cations (terpy is 2,2':6',2''-terpyridine) and [C(CN)₃]^- anions. In the cation, the Co^II atom is coordinated by two terpy molecules, giving a distorted octahedral geometry. The tricyanomethanide anions are not directly coordinated to the Co^II atom, but some weak C-HN hydrogen bonds involving the terminal N atoms of the tricyaomethanide ions and the terpyridine H atoms link anions and cations building a three-dimensional network.
