Materials Data on Ce(CrSi)2 by Materials Project
CeCr2Si2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ce3+ is bonded in a body-centered cubic geometry to eight equivalent Si4- atoms. All Ce–Si bond lengths are 3.06 Å. Cr+2.50+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing CrSi4 tetrahedra. All Cr–Si bond lengths are 2.42 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Ce3+, four equivalent Cr+2.50+, and one Si4- atom. The Si–Si bond length is 2.52 Å.
