Used in the preparation of a new complex, Co(OESPz), which offers the possibility of intermolecular ferromagnetic interactions.1
Crystallise it from water (1mL/g) by partial evaporation in a desiccator. The anhydrous salt is soluble in EtOH, Me2CO, MeOAc to form blue-coloured solutions. [Glemser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1517 1965.]
Not flammable. POISONOUS FUMES ARE PRODUCED WHEN HEATED TO DECOMPOSITION. When heated to decomposition can give off highly toxic fumes of Br.
Reddish violet crystalline powder
COBALT(II) BROMIDE is a red violet crystalline solid. COBALT(II) BROMIDE is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. COBALT(II) BROMIDE is used as a catalyst in the production of other chemicals.
Air & Water Reactions
SOLID: Irritating to skin and eyes. Harmful if swallowed.
Acidic salts, such as COBALT(II) BROMIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. When heated to decomposition can give off highly toxic fumes of Br [USCG, 1999].
