Barium chloride fluoride is an inorganic chemical compound of barium, chlorine, and fluorine.[1] Its chemical formula is BaClF.[2][3] The compound naturally occurs as Zhangpeishanite mineral of the Matlockite group.[4] One of the deposits where the mineral is mined is Bayan Obo in China.[5]

Synthesis

Barium fluoride can be prepared by precipitating barium chloride and ammonium fluoride in a solution.

Physical properties

Barium chloride fluoride forms white crystals.[6] The crystal structure of BaClF is a tetragonal distortion of that of fluoride type BaF

.[7]

The compound is poorly soluble in water.[8]
