Lead fluorobromide or lead fluoride bromide is an inorganic compound of lead, fluorine, and bromine with the chemical formula PbFBr.[1] The compound is a mixed halide of lead, meaning it contains both fluoride and bromide ions.
Synthesis
The compound can be obtained by melting PbF2 with PbBr2 while other methods are also known.[2]
- PbF2 + PbBr2 → 2PbFBr
Physical properties
The compound forms crystals of layered tetragonal system, space group P4/mmm. The unit cell has dimensions a = 4.18 Å, c = 7.59 Å, and Z = 2.[3]
