Materials Data on ZrSiPd by Materials Project

Abstract

ZrPdSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Zr2+ is bonded to five equivalent Si4- atoms to form distorted ZrSi5 trigonal bipyramids that share corners with eight equivalent PdSi4 tetrahedra, corners with eight equivalent ZrSi5 trigonal bipyramids, edges with six equivalent PdSi4 tetrahedra, and edges with six equivalent ZrSi5 trigonal bipyramids. There are a spread of Zr–Si bond distances ranging from 2.78–2.85 Å. Pd2+ is bonded to four equivalent Si4- atoms to form PdSi4 tetrahedra that share corners with eight equivalent PdSi4 tetrahedra, corners with eight equivalent ZrSi5 trigonal bipyramids, edges with two equivalent PdSi4 tetrahedra, and edges with six equivalent ZrSi5 trigonal bipyramids. There are a spread of Pd–Si bond distances ranging from 2.49–2.58 Å. Si4- is bonded in a 9-coordinate geometry to five equivalent Zr2+ and four equivalent Pd2+ atoms.
