Th6CoBr15 crystallizes in the cubic Im-3m space group. The structure consists of a Th6CoBr15 framework. Th(1) is bonded to one Co(1), one Br(1), and four equivalent Br(2) atoms to form a mixture of edge and corner-sharing ThCoBr5 octahedra. The corner-sharing octahedra are not tilted. Co(1) is bonded in an octahedral geometry to six equivalent Th(1) atoms. There are two inequivalent Br sites. In the first Br site, Br(2) is bonded in an L-shaped geometry to two equivalent Th(1) atoms. In the second Br site, Br(1) is bonded in a linear geometry to two equivalent Th(1) atoms.
