The structure described by Ba(MgGe)2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a 16-coordinate geometry to eight equivalent Mg(1) and eight equivalent Ge(1) atoms. Mg(1) is bonded to four equivalent Ba(1) and four equivalent Ge(1) atoms to form a mixture of corner, face, and edge-sharing MgBa4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ba(1), four equivalent Mg(1), and one Ge(1) atom. is represented by the CIF card [CIF]
