Lead fluorochloride or lead fluoride chloride is an inorganic compound of lead, fluorine, and chlorine with the chemical formula .mw-parser-output .template-chem2-su{display:inline-block;font-size:80%;line-height:1;vertical-align:-0.35em}.mw-parser-output .template-chem2-su>span{display:block;text-align:left}.mw-parser-output sub.template-chem2-sub{font-size:80%;vertical-align:-0.35em}.mw-parser-output sup.template-chem2-sup{font-size:80%;vertical-align:0.65em}PbFCl. The compound is a mixed halide of lead, meaning it contains both fluoride and chloride ions.

The mineral matlockite with the chemical formula PbFCl was discovered in the early 1800s at Bage Mine in Bolehill near Matlock, alongside phosgenite and anglesite specimens. While phosgenite had already been identified by that time, it appears that matlockite was not officially recognized as a distinct new mineral for approximately 50 years after its discovery.

The compound can be obtained by melting PbF2 with PbCl2 while other methods are also known.

PbF2 + PbCl2 → 2PbFCl

An exchange reaction of acidified solutions of lead nitrate, potassium chloride, and potassium fluoride:

Pb(NO3)2 + KF + KCl → PbClF + 2KNO3

The compound forms crystals of layered tetragonal system, space group P4/mmm. Unit cell dimensions are a = 4.111 Å, c = 7.226 Å, V = 122.1 Å3.

Pure lead fluorochloride is transparent between 270 and 800 nm. It is fluorescent under UV light.
