· AsCl3

Arsenic trichloride (AsCl₃) is an inorganic ceramic compound that exists primarily as a molecular solid with layered crystal structure. While not commonly encountered in conventional structural applications, AsCl₃ is of interest in materials research for its potential in layered material systems and semiconductor-adjacent applications, particularly in contexts involving arsenic-based compounds for optoelectronics and thin-film technologies.
