Four cobalt(III) azide complexes, [Co(III)(bpy)2(N3)2]X [X = p-toluenesulfonate (1), tetrafluoroborate (2), chloride (3)] and [Co(III)(bpy)2(N3)2][Co(III)(bpy)(N3)4] (4), were prepared under ambient conditions and their structures have been determined. Complex 4 is structurally interesting; it accommodates four azides in the anionic part of the complex. Complexes 1–4 show exothermic processes at <250 °C, and compound 4 reductively decomposes at 221 °C.
