CdGe4C4NS10C4N crystallizes in the tetragonal I-4 space group. The structure consists of two tetramethylammonium molecules inside a CdGe4C4NS10 framework. In the CdGe4C4NS10 framework, Cd(1) is bonded to four equivalent S(2) atoms to form CdS4 tetrahedra that share corners with four equivalent Ge(1)S4 tetrahedra. Ge(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form GeS4 tetrahedra that share  a cornercorner with one Cd(1)S4 tetrahedra and corners with three equivalent Ge(1)S4 tetrahedra. C(1) is bonded in a 3-coordinate geometry to one C(1), one N(1), and one S(2) atom. N(1) is bonded in a 4-coordinate geometry to four equivalent C(1) atoms. There are three inequivalent S sites. In the first S site, S(3) is bonded in a water-like geometry to two equivalent Ge(1) atoms. In the second S site, S(1) is bonded in a water-like geometry to two equivalent Ge(1) atoms. In the third S site, S(2) is bonded in a 3-coordinate geometry to one Cd(1), one Ge(1), and one C(1) atom.
