Ca(AgGe)2 crystallizes in the tetragonal I4/mmm space group. Ca(1) is bonded in a 16-coordinate geometry to eight equivalent Ag(1) and eight equivalent Ge(1) atoms. Ag(1) is bonded to four equivalent Ca(1), four equivalent Ag(1), and four equivalent Ge(1) atoms to form a mixture of distorted corner, edge, and face-sharing AgCa4Ag4Ge4 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ca(1), four equivalent Ag(1), and one Ge(1) atom.
