Ba(CdGe)2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 16-coordinate geometry to eight equivalent Cd(1) and eight equivalent Ge(1) atoms. Cd(1) is bonded to four equivalent Ba(1) and four equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing CdBa4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ba(1), four equivalent Cd(1), and one Ge(1) atom.
