Materials Data on CeMnSi2Pd by Materials Project

Abstract

CeMnPdSi2 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Ce4+ is bonded in a distorted body-centered cubic geometry to eight equivalent Si4- atoms. All Ce–Si bond lengths are 3.15 Å. Mn2+ is bonded to four equivalent Si4- atoms to form MnSi4 tetrahedra that share corners with four equivalent MnSi4 tetrahedra and edges with four equivalent PdSi4 tetrahedra. All Mn–Si bond lengths are 2.40 Å. Pd2+ is bonded to four equivalent Si4- atoms to form PdSi4 tetrahedra that share corners with four equivalent PdSi4 tetrahedra and edges with four equivalent MnSi4 tetrahedra. All Pd–Si bond lengths are 2.40 Å. Si4- is bonded in a 9-coordinate geometry to four equivalent Ce4+, two equivalent Mn2+, two equivalent Pd2+, and one Si4- atom. The Si–Si bond length is 2.47 Å.
