摘要：

In the mononuclear title complex, [Co(N-3)(2)(C12H8N4S)(2)], the cobalt(II) atom is located on an inversion centre and displays an axially weakly compressed octahedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis(pyridin-2-yl)-1,3,4-thiadiazole ligands, whereas the axial positions are occupied by N atoms of the azide anions. The thiadiazole and pyridine rings linked to the metal are almost coplanar, with a maximum deviation from the mean plane of 0.0273 (16) angstrom. The cohesion of the crystal is ensured by weak C-H center dot center dot center dot N hydrogen bonds and by pi-pi interactions between pyridine rings [intercentroid distance = 3.6356 (11) angstrom], forming a layered arrangement parallel to (001). The structure of the title compound is isotypic with that of the analogous nickel(II) complex [Laachir et al. (2013). Acta Cryst. E69, m351-m352].
