Materials Data on Ce(GeAu)2 by Materials Project
CeAu2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ce is bonded in a 8-coordinate geometry to eight equivalent Au and eight equivalent Ge atoms. All Ce–Au bond lengths are 3.45 Å. All Ce–Ge bond lengths are 3.36 Å. Au is bonded to four equivalent Ce and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing AuCe4Ge4 tetrahedra. All Au–Ge bond lengths are 2.64 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Ce, four equivalent Au, and one Ge atom. The Ge–Ge bond length is 2.42 Å.
