Title: Materials Data on Yb(SiAg)2 by Materials Project

Abstract

YbAg2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb3+ is bonded to eight equivalent Si4- atoms to form YbSi8 hexagonal bipyramids that share corners with sixteen equivalent AgSi4 tetrahedra, edges with four equivalent YbSi8 hexagonal bipyramids, edges with eight equivalent AgSi4 tetrahedra, and faces with four equivalent YbSi8 hexagonal bipyramids. All Yb–Si bond lengths are 3.23 Å. Ag+2.50+ is bonded to four equivalent Si4- atoms to form AgSi4 tetrahedra that share corners with eight equivalent YbSi8 hexagonal bipyramids, corners with four equivalent AgSi4 tetrahedra, edges with four equivalent YbSi8 hexagonal bipyramids, and edges with four equivalent AgSi4 tetrahedra. All Ag–Si bond lengths are 2.60 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Yb3+, four equivalent Ag+2.50+, and one Si4- atom. The Si–Si bond length is 2.28 Å.
