The material described by Nb6SnSi crystallizes in the cubic Pm-3 space group. Nb(1) is bonded in a 6-coordinate geometry to two equivalent Nb(1), two equivalent Sn(1), and two equivalent Si(1) atoms. Sn(1) is bonded to twelve equivalent Nb(1) atoms to form SnNb12 cuboctahedra that share edges with six equivalent Sn(1)Nb12 cuboctahedra and faces with eight equivalent Si(1)Nb12 cuboctahedra. Si(1) is bonded to twelve equivalent Nb(1) atoms to form SiNb12 cuboctahedra that share edges with six equivalent Si(1)Nb12 cuboctahedra and faces with eight equivalent Sn(1)Nb12 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
