Materials Data on Yb(CrSi)2 by Materials Project
Yb(CrSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb2+ is bonded in a body-centered cubic geometry to eight equivalent Si4- atoms. All Yb–Si bond lengths are 2.98 Å. Cr3+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing CrSi4 tetrahedra. All Cr–Si bond lengths are 2.41 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Yb2+, four equivalent Cr3+, and one Si4- atom. The Si–Si bond length is 2.48 Å.
