The material structure described by NbSn3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Nb(1) is bonded to twelve equivalent Sn(1) atoms to form NbSn12 cuboctahedra that share corners with six equivalent Nb(1)Sn12 cuboctahedra, corners with twelve equivalent Sn(1)Nb4Sn8 cuboctahedra, edges with eighteen equivalent Sn(1)Nb4Sn8 cuboctahedra, faces with eight equivalent Nb(1)Sn12 cuboctahedra, and faces with twelve equivalent Sn(1)Nb4Sn8 cuboctahedra. Sn(1) is bonded to four equivalent Nb(1) and eight equivalent Sn(1) atoms to form distorted SnNb4Sn8 cuboctahedra that share corners with four equivalent Nb(1)Sn12 cuboctahedra, corners with fourteen equivalent Sn(1)Nb4Sn8 cuboctahedra, edges with six equivalent Nb(1)Sn12 cuboctahedra, edges with twelve equivalent Sn(1)Nb4Sn8 cuboctahedra, faces with four equivalent Nb(1)Sn12 cuboctahedra, and faces with sixteen equivalent Sn(1)Nb4Sn8 cuboctahedra. is represented by the CIF card [CIF]
