Materials Data on Th(GeAu)2 by Materials Project
Th(AuGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Th is bonded in a 8-coordinate geometry to eight equivalent Au and eight equivalent Ge atoms. All Th–Au bond lengths are 3.46 Å. All Th–Ge bond lengths are 3.37 Å. Au is bonded to four equivalent Th and four equivalent Ge atoms to form a mixture of distorted edge, face, and corner-sharing AuTh4Ge4 tetrahedra. All Au–Ge bond lengths are 2.64 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Th, four equivalent Au, and one Ge atom. The Ge–Ge bond length is 2.45 Å.
