叠氮化钴是一种无机化合物，化学式为{Co(μ-N₃)₂}_n。^[2]它可由硝酸钴和叠氮化钠在酸化的溶液中反应，沉淀得到；^[3]或由八羰基二钴和叠氮化碘反应制得。^[1]

Co₂(CO)₈ + 4 IN₃ → 2 Co(N₃)₂ + 8 CO + 2 I₂

它也是五唑化钴八水合物（Co(N₅)₂(H₂O)₄·4H₂O）的热分解产物。^[4]它可以形成配离子CoN₃⁺和[Co(N₃)₄]²⁻，后者可以[(C₆H₅)₄E]₂[Co(N₃)₄]（E=P, As）的形式分离出来。^[5]

三价钴的化合物Co₂(μ-N₃)₂(N₃)₄（CAS号：150117-01-4）是已知的，它通过Co(NH₃)₃(N₃)₃光解得到。^[2]
