Materials Data on NbSiPt by Materials Project
NbPtSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Nb2+ is bonded to five equivalent Si4- atoms to form distorted NbSi5 trigonal bipyramids that share corners with eight equivalent PtSi4 tetrahedra, corners with eight equivalent NbSi5 trigonal bipyramids, edges with six equivalent PtSi4 tetrahedra, and edges with six equivalent NbSi5 trigonal bipyramids. There are a spread of Nb–Si bond distances ranging from 2.67–2.81 Å. Pt2+ is bonded to four equivalent Si4- atoms to form PtSi4 tetrahedra that share corners with eight equivalent PtSi4 tetrahedra, corners with eight equivalent NbSi5 trigonal bipyramids, edges with two equivalent PtSi4 tetrahedra, and edges with six equivalent NbSi5 trigonal bipyramids. There are a spread of Pt–Si bond distances ranging from 2.42–2.53 Å. Si4- is bonded in a 9-coordinate geometry to five equivalent Nb2+ and four equivalent Pt2+ atoms.
