Beryllium bromide

Beryllium bromide is the chemical compound with the formula BeBr2. It is very hygroscopic and dissolves well in water. The compound is a polymer with tetrahedral Be centres.
Preparation and reactions.
It can be prepared by reacting beryllium metal with elemental bromine at temperatures of 500 °C to 700 °C:
Beryllium bromide is also formed when treating beryllium oxide with hydrobromic acid:
It hydrolizes slowly in water: BeBr2 + 2 H2O → 2 HBr + Be(OH)2
Safety.
Beryllium compounds are toxic if inhaled or ingested.
