The structure described by Ag2CdGeS4 is Stannite-like structured and crystallizes in the orthorhombic Pna2_1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form AgS4 tetrahedra that share corners with four equivalent Ag(2)S4 tetrahedra, corners with four equivalent Cd(1)S4 tetrahedra, and corners with four equivalent Ge(1)S4 tetrahedra. In the second Ag site, Ag(2) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form AgS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra, corners with four equivalent Cd(1)S4 tetrahedra, and corners with four equivalent Ge(1)S4 tetrahedra. Cd(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form CdS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra, corners with four equivalent Ag(2)S4 tetrahedra, and corners with four equivalent Ge(1)S4 tetrahedra. Ge(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form GeS4 tetrahedra that share corners with four equivalent Ag(1)S4 tetrahedra, corners with four equivalent Ag(2)S4 tetrahedra, and corners with four equivalent Cd(1)S4 tetrahedra. There are four inequivalent S sites. In the first S site, S(1) is bonded to one Ag(1), one Ag(2), one Cd(1), and one Ge(1) atom to form corner-sharing SCdAg2Ge tetrahedra. In the second S site, S(2) is bonded to one Ag(1), one Ag(2), one Cd(1), and one Ge(1) atom to form corner-sharing SCdAg2Ge tetrahedra. In the third S site, S(3) is bonded to one Ag(1), one Ag(2), one Cd(1), and one Ge(1) atom to form corner-sharing SCdAg2Ge tetrahedra. In the fourth S site, S(4) is bonded to one Ag(1), one Ag(2), one Cd(1), and one Ge(1) atom to form corner-sharing SCdAg2Ge tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
