About ClH2HoO2

ClH2HoO2 is a rare-earth-based compound characterized by its insulating electronic nature and high thermodynamic stability. As a member of the holmium halide hydroxide family, it maintains a robust structural arrangement that positions it on the convex hull, indicating significant stability under standard conditions.

This material serves as an important subject for understanding the coordination chemistry of lanthanide centers in the presence of mixed anionic environments. Its wide-band-gap nature makes it a compelling candidate for specialized optical or electronic applications where insulating behavior is required.
