Materials Data on Sc3V2Si3 by Materials Project
Sc3V2Si3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. Sc+2.67+ is bonded to five equivalent Si4- atoms to form a mixture of distorted edge and corner-sharing ScSi5 trigonal bipyramids. There are a spread of Sc–Si bond distances ranging from 2.67–2.86 Å. V2+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. All V–Si bond lengths are 2.66 Å. Si4- is bonded in a 9-coordinate geometry to five equivalent Sc+2.67+ and four equivalent V2+ atoms.
