In the title complex, [Co(NCO)(2)(C(10)H(8)N(2))(2)], the Co atom is coordinated by four N atoms from two 2,2'-bipyridyl ligands and two N atoms from two cyanate anions in a distorted octa-hedral geometry. The Co atom lies on a twofold rotation axis. The average Co-N bond length is 2.126 (7) Å. Weak inter-molecular C-H⋯O inter-actions lead to the formation of a three-dimensional network.
