In the crystal structure of the binuclear title complex, [Co(N3)2(C12H8N2)]n, each CoII cation is coordinated by two N atoms from one chelating 1,10-phenanthroline ligand and four azide ligands in a slightly distorted octahedral coordination. The two CoII cations of the binuclear complex are related by an inversion centre and are bridged by two symmetry-related azide ligands in both [mu]1,1 and [mu]1,3 modes. The [mu]1,3 bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the [mu]1,1 bridging mode is responsible for the formation of the binuclear CoII complex.
