The compound described by Sm(VAl10)2 crystallizes in the cubic Fd-3m space group. Sm(1) is bonded in a 16-coordinate geometry to four equivalent Al(3) and twelve equivalent Al(2) atoms. V(1) is bonded to six equivalent Al(1) and six equivalent Al(2) atoms to form VAl12 cuboctahedra that share corners with six equivalent V(1)Al12 cuboctahedra, edges with eighteen equivalent Al(2)SmAl10V cuboctahedra, and faces with six equivalent Al(2)SmAl10V cuboctahedra. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded in a 12-coordinate geometry to two equivalent V(1), four equivalent Al(1), and six equivalent Al(2) atoms. In the second Al site, Al(3) is bonded in a distorted linear geometry to two equivalent Sm(1) and twelve equivalent Al(2) atoms. In the third Al site, Al(2) is bonded to one Sm(1), one V(1), two equivalent Al(3), three equivalent Al(1), and five equivalent Al(2) atoms to form distorted AlSmAl10V cuboctahedra that share corners with fifteen equivalent Al(2)SmAl10V cuboctahedra, edges with two equivalent Al(2)SmAl10V cuboctahedra, edges with three equivalent V(1)Al12 cuboctahedra,  a faceface with one V(1)Al12 cuboctahedra, and faces with fifteen equivalent Al(2)SmAl10V cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
