The structure described by Ca(AuGe)2 crystallizes in the tetragonal I4/mmm space group. Ca(1) is bonded in a 16-coordinate geometry to eight equivalent Au(1) and eight equivalent Ge(1) atoms. Au(1) is bonded in a 4-coordinate geometry to four equivalent Ca(1) and four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ca(1), four equivalent Au(1), and one Ge(1) atom. is represented by the CIF file [CIF]
