See nickel. | [Chemical Properties]
(1) Brownish-yellow solid or yellow,
lustrous scales.(2) Deliquescent, greenish scales; loses 3H2O at 300C. Soluble
in water, alcohol, ether, and ammonium hydroxide. | [Chemical Properties]
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 both cases the Ni-Br distance is 2.6 and the Ni-O distance 2.0 ?. | [Uses]
It is used in Soporific and sedatives pharmaceutical Industry, Photosensitive industry, Analytical Chemistry, and also electrolyte in high energy battery. | [Preparation]
Anhydrous NiBr2 is most conveniently prepared by the action of
bromine on nickel, either at red heat or in ethereal solution at room temperature74 or by
dehydration of the hexahydrate at about 140°. It crystallizes with the CdCl2 type structure, the nickel atoms being surrounded octahedrally by bromine atoms at 2.57 ?. | [reaction suitability]
reagent type: catalyst
core: nickel |
