Description

(1) Brownish-yellow solid or yellow, lustrous scales.(2) Deliquescent, greenish scales; loses 3H2O at 300C. Soluble in water, alcohol, ether, and ammonium hydroxide. The green hexahydrate NiBr2-6H2O readily evolves water; crystallization from aqueous solutions above 29° yields the trihydrate NiBr2-3H2O. The hexahydrate can be dehydrated to a dihydrate over concentrated sulphuric acid at 5°. The environment of the nickel atoms in NiBr2-6H20 is 2Br and 4H20 and in NiBr2-2H20 4Br and 2H20 ; in bot
