Abstract
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 formulaM4A2X3(M= Cd, Hg;A= P, As, Sb;X= Cl, Br, I) and contains two independent As atoms on special positions with site symmetry -3 and two independent Cd atoms, of which one is on a special position with site symmetry -3. The Cd4As2Br3structure consists of AsCd4tetrahedra sharing vertices with isolated As2Cd6octahedra that contain As–As dumbbells in the centre of the octahedron. The Br atoms are located in the voids of this three-dimensional arrangement and bridge the different polyhedra through Cd...Br contacts.
