Materials Data on V6SiSn by Materials Project

Abstract

V6SnSi crystallizes in the cubic Pm-3 space group. The structure is three-dimensional. V is bonded in a 6-coordinate geometry to two equivalent V, two equivalent Sn, and two equivalent Si atoms. There are one shorter (2.27 Å) and one longer (2.57 Å) V–V bond lengths. Both V–Sn bond lengths are 2.74 Å. Both V–Si bond lengths are 2.67 Å. Sn is bonded to twelve equivalent V atoms to form SnV12 cuboctahedra that share edges with six equivalent SnV12 cuboctahedra and faces with eight equivalent SiV12 cuboctahedra. Si is bonded to twelve equivalent V atoms to form SiV12 cuboctahedra that share edges with six equivalent SiV12 cuboctahedra and faces with eight equivalent SnV12 cuboctahedra.
