Pb5VO43Cl

Pb5VO43Cl, written as Pb5(VO4)3Cl in more conventional chemical notation, is a lead-containing oxide-vanadate chloride that belongs to the apatite family of minerals and solid-state compounds. It fits the general apatite formula A5(TO4)3X, where A is a large cation, T is a tetrahedrally coordinated pentavalent unit, and X is an halide ion. For Pb5(VO4)3Cl, A is Pb2+, T is V in VO4 tetrahedra, and X is Cl−.

In the crystal structure, VO4 tetrahedra and Pb-centered polyhedra form a three-dimensional framework characteristic of apatites. The structure incorporates channels along the c-axis that can accommodate the chloride anion. This arrangement yields a relatively open lattice that can influence properties such as ionic mobility and dielectric behavior, while maintaining overall electrical neutrality through the Pb2+, VO4, and Cl− constituents.

Synthesis and characterization of Pb5(VO4)3Cl are typically reported within solid-state chemistry and crystallography studies. It is usually prepared by high-temperature reactions involving lead oxide or lead compounds, vanadium oxide sources, and chloride-containing reagents, followed by controlled cooling to promote crystallization. The material has been examined using X-ray diffraction and spectroscopic techniques to confirm its apatite-type framework and to study its structural parameters.

Safety and handling considerations are important due to the presence of lead. Pb5(VO4)3Cl is mainly of interest to researchers studying apatite-type materials, solid-state chemistry, and structure–property relationships in lead vanadate systems.
