Materials Data on VSn3 by Materials Project

VSn3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. V is bonded to twelve equivalent Sn atoms to form VSn12 cuboctahedra that share corners with six equivalent VSn12 cuboctahedra, corners with twelve equivalent SnV4Sn8 cuboctahedra, edges with eighteen equivalent SnV4Sn8 cuboctahedra, faces with eight equivalent VSn12 cuboctahedra, and faces with twelve equivalent SnV4Sn8 cuboctahedra. There are six shorter (3.12 Å) and six longer (3.19 Å) V–Sn bond lengths. Sn is bonded to four equivalent V and eight equivalent Sn atoms to form distorted SnV4Sn8 cuboctahedra that share corners with four equivalent VSn12 cuboctahedra, corners with fourteen equivalent SnV4Sn8 cuboctahedra, edges with six equivalent VSn12 cuboctahedra, edges with twelve equivalent SnV4Sn8 cuboctahedra, faces with four equivalent VSn12 cuboctahedra, and faces with sixteen equivalent SnV4Sn8 cuboctahedra. There are a spread of Sn–Sn bond distances ranging from 3.00–3.27 Å.
