Materials Data on Th(CrGe)2 by Materials Project
ThCr2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Th is bonded in a 8-coordinate geometry to eight equivalent Cr and eight equivalent Ge atoms. All Th–Cr bond lengths are 3.38 Å. All Th–Ge bond lengths are 3.23 Å. Cr is bonded to four equivalent Th and four equivalent Ge atoms to form a mixture of edge, face, and corner-sharing CrTh4Ge4 tetrahedra. All Cr–Ge bond lengths are 2.48 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Th, four equivalent Cr, and one Ge atom. The Ge–Ge bond length is 2.63 Å.
