Cd4As2Br3

Cd4As2Br3

Single crystals of Cd4As2Br3 (tetracadmium biarsenide tribromide) were grown by a chemical transport reaction. The structure is isotypic with the members of the cadmium and mercury pnictidohalides family with general formula M4A2X3 (M = Cd, Hg; A = P, As, Sb; X = Cl, Br, I) and contains two independ...
