Besides these compounds, in which diammoniacuprictim is found, a large number 

 of compounds containing one at. cupricura and two mol. NH 3 are also known, but not 

 their atoraical conrposition. 



They are as follows: R=Cu . 2NH 3 



1. Chloride R(V) 



2. Chloride with Chloride of ammonium RC1 4 . 2NH 4 ") 



3. Ferrocyanide R 2 Cy 6 Fe + H 2 3 )
