The compound described by Co4SnSb12 crystallizes in the cubic Im-3 space group. Co(1) is bonded to six equivalent Sb(1) atoms to form CoSb6 octahedra that share corners with six equivalent Co(1)Sb6 octahedra and faces with two equivalent Sn(1)Sb12 cuboctahedra. The corner-sharing octahedral tilt angles are 52°. Sn(1) is bonded to twelve equivalent Sb(1) atoms to form SnSb12 cuboctahedra that share faces with eight equivalent Co(1)Sb6 octahedra. Sb(1) is bonded in a 2-coordinate geometry to two equivalent Co(1) and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
