Vanadium(II) bromide is a inorganic compound with the formula VBr₂. It adopts the cadmium iodide structure, featuring octahedral V(II) centers.^[1] A hexahydrate is also known. The hexahydrate undergoes partial dehydration to give the tetrahydrate. Both the hexa- and tetrahydrates are bluish in color.^[2] The compound is produced by the reduction of vanadium(III) bromide with hydrogen.
