There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one S(1), one S(3), one S(5), and one S(6) atom to form GeS4 tetrahedra that share corners with two equivalent Cd(1)S4 tetrahedra, corners with two equivalent Ge(2)S4 tetrahedra,  a cornercorner with one Na(1)S5 trigonal bipyramid, and  an edgeedge with one Na(1)S5 trigonal bipyramid.
