Cobalt azoimide

Cobalt Triazide (formerly call Cobalt Tri-nitride or Cobalt Azoimide) Co(N,)j, raw 142.99, N58.78% red-brn crysts (anhyd), mp det 148° (0.02 g in 5 sec) (Ref 5), hygroscopic and easily hydrolyzed (Ref 4). The basic cobalt azide, Co(OH)N, was first prepd in 1898 by Curtius Rissom (Ref 1). An aq soln of cobalt azide was studied by Dennis Isham (Ref 2). The anhyd salt, prepd by ihe action of cobaitous carbonate on hydrazoic acid, was prepd by Wohler (Ref 3) and by Wohler Si Martin MptKrvrl C nf nr hrt... 

Cobalt Azoimide, Co(N3)2, and a Basic Azoimide, N3-Co.OH, have been obtained in mixture by Curtius3 as a violet powder. Potassium cobalto-azoimide, KN3.Co(N3)2, is obtained as a bright blue crystalline precipitate when concentrated solutions of the two azo-imides are mixed. It explodes at 225° C. The ammonium analogue, NH4N3. Co(N3)2, has also been prepared.
