Materials Data on V6SiC by Materials Project

Abstract

V6SiC 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 Si, and two equivalent C atoms. There are one shorter (2.22 Å) and one longer (2.35 Å) V–V bond lengths. Both V–Si bond lengths are 2.57 Å. Both V–C bond lengths are 2.54 Å. 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 CV12 cuboctahedra. C is bonded to twelve equivalent V atoms to form CV12 cuboctahedra that share edges with six equivalent CV12 cuboctahedra and faces with eight equivalent SiV12 cuboctahedra.
