· AuBr

AuBr is an intermetallic compound combining gold and bromine, representing a rare metal-halide material with potential applications in advanced materials research. This compound belongs to an experimental class of materials being investigated for layered or two-dimensional structural properties, as evidenced by its measurable exfoliation energy. While not yet established in mainstream industrial production, AuBr and related gold-halide compounds are of interest to researchers exploring novel electronic, catalytic, or structural properties that differ fundamentally from conventional metallic alloys.
