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 ?.
