Barium Hydroxide Octahydrate can be prepared by dissolving barium oxide (BaO) in water: BaO + H2O → Ba(OH)2
It crystallises as the octahydrate, which converts to the monohydrate upon heating in air.
At 100 °C in a vacuum, the monohydrate will yield BaO and water.
The monohydrate adopts a layered structure (see picture above).
The Ba2+ centers adopt a square antiprismatic geometry.
Each Ba2+ center is bound by two water ligands and six hydroxide ligands, which are respectively doubly and triply bridging to neighboring Ba2+ centre sites.
In the octahydrate, the individual Ba2+ centers are again eight coordinate but do not share ligands.
