Title: Materials Data on VCoSi by Materials Project

Abstract

VCoSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. V2+ is bonded to five equivalent Si4- atoms to form distorted VSi5 trigonal bipyramids that share corners with eight equivalent CoSi4 tetrahedra, corners with eight equivalent VSi5 trigonal bipyramids, edges with six equivalent CoSi4 tetrahedra, and edges with six equivalent VSi5 trigonal bipyramids. There are a spread of V–Si bond distances ranging from 2.51–2.56 Å. Co2+ is bonded to four equivalent Si4- atoms to form CoSi4 tetrahedra that share corners with eight equivalent CoSi4 tetrahedra, corners with eight equivalent VSi5 trigonal bipyramids, edges with two equivalent CoSi4 tetrahedra, and edges with six equivalent VSi5 trigonal bipyramids. There are two shorter (2.24 Å) and two longer (2.28 Å) Co–Si bond lengths. Si4- is bonded in a 9-coordinate geometry to five equivalent V2+ and four equivalent Co2+ atoms.
