Materials Data on Y(CrSi)2 by Materials Project
Y(CrSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Y3+ is bonded in a body-centered cubic geometry to eight equivalent Si4- atoms. All Y–Si bond lengths are 2.99 Å. Cr+2.50+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing CrSi4 tetrahedra. All Cr–Si bond lengths are 2.40 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Y3+, four equivalent Cr+2.50+, and one Si4- atom. The Si–Si bond length is 2.47 Å.
