Materials Data on Co4SnSb12 by Materials Project
Co4SnSb12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Co2+ is bonded to six equivalent Sb1- atoms to form CoSb6 octahedra that share corners with six equivalent CoSb6 octahedra and faces with two equivalent SnSb12 cuboctahedra. The corner-sharing octahedral tilt angles are 52°. All Co–Sb bond lengths are 2.56 Å. Sn4+ is bonded to twelve equivalent Sb1- atoms to form SnSb12 cuboctahedra that share faces with eight equivalent CoSb6 octahedra. All Sn–Sb bond lengths are 3.38 Å. Sb1- is bonded in a 2-coordinate geometry to two equivalent Co2+ and one Sn4+ atom.
