The title compound, [Co(C2N3)2(C3H7NO)2]n, is a triclinic polymorph of the previously reported monoclinic structure [Tong et al. (2003[Tong, M.-L., Zhou, A.-J., Hu, S., Chen, X.-M. & Ng, S. W. (2003). Acta Cryst. E59, m405-m407.]). Acta Cryst. E59, m405-m407]. The CoII ion lies on an inversion centre and adopts an almost regular octahedral N4O2 coordination geometry. Adjacent CoII atoms are connected by two bridging dicyanamide ligands, resulting in the formation of neutral chains parallel to the b axis. The title complex is isotypic with the MnII analogue but not with the NiII analogue.
