CdGeAs2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Cd(1) is bonded to four equivalent As(1) atoms to form CdAs4 tetrahedra that share corners with four equivalent Cd(1)As4 tetrahedra and corners with eight equivalent Ge(1)As4 tetrahedra. Ge(1) is bonded to four equivalent As(1) atoms to form GeAs4 tetrahedra that share corners with four equivalent Ge(1)As4 tetrahedra and corners with eight equivalent Cd(1)As4 tetrahedra. As(1) is bonded to two equivalent Cd(1) and two equivalent Ge(1) atoms to form corner-sharing AsCd2Ge2 tetrahedra.
