About CaCl3Rb

CaCl3Rb is a complex halide compound composed of calcium, chlorine, and rubidium. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement within its chemical system. Its electronic character is defined by a wide band gap, classifying it as an insulator with significant potential for specialized dielectric or optical applications.

This material is characterized by a high degree of structural diversity, with multiple reported configurations across various databases. Its stability and insulating nature make it an interesting subject for fundamental studies in solid-state chemistry, particularly for researchers investigating ternary halide systems and their underlying lattice dynamics.
