ThCr2Ge2 crystallizes in the tetragonal I4/mmm space group. Th(1) is bonded in a 16-coordinate geometry to eight equivalent Cr(1) and eight equivalent Ge(1) atoms. Cr(1) is bonded to four equivalent Th(1) and four equivalent Ge(1) atoms to form a mixture of edge, corner, and face-sharing CrTh4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Th(1), four equivalent Cr(1), and one Ge(1) atom.
