About Matlockite
PbClF is a distinct inorganic compound characterized by its insulating electronic nature and high thermodynamic stability. As a member of the halide family, it occupies a significant position on the convex hull, indicating robust structural integrity under standard conditions.
Researchers value this material for its structural complexity, as evidenced by the numerous reported crystal structures across major databases. Its unique arrangement of lead, chlorine, and fluorine ions makes it a subject of interest for fundamental studies in solid-state chemistry and materials science.
Key Properties
Cross-validated computational properties for Matlockite, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom.
