    CoBr 2 ·6H 2 O → CoBr 2 ·2H 2 O + 4 H 2 O. Further heating to 130 °C produces the anhydrous form: CoBr 2 ·2H 2 O → CoBr 2 + 2 H 2 O. The anhydrous form melts at 678 °C. [2] [3] At higher temperatures, cobalt(II) bromide reacts with oxygen, forming cobalt(II,III) oxide and bromine vapor. The tetrahydrate is molecular, with the formula ...

    Cobalt(II) azide (Co(N 3) 2) is another binary compound of cobalt and nitrogen that can explode when heated. Cobalt(II) and azide can form Co(N 3) 2− 4 complexes. [9] Cobalt pentazolide Co(N 5) 2 was discovered in 2017, and it exists in the form of the hydrate [Co(H 2 O) 4 (N 5) 2]·4H 2 O. It decomposes at 50~145 °C to form cobalt(II) azide ...
