The material structure described by Pb4Ga4GeS12 crystallizes in the tetragonal P-42_1c space group. Ga(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form GaS4 tetrahedra that share  a cornercorner with one Ge(1)S4 tetrahedra and corners with two equivalent Ga(1)S4 tetrahedra. Pb(1) is bonded in a 5-coordinate geometry to one S(2), one S(3), and three equivalent S(1) atoms. Ge(1) is bonded to four equivalent S(2) atoms to form GeS4 tetrahedra that share corners with four equivalent Ga(1)S4 tetrahedra. There are three inequivalent S sites. In the first S site, S(3) is bonded in a distorted water-like geometry to two equivalent Ga(1) and one Pb(1) atom. In the second S site, S(1) is bonded in a distorted single-bond geometry to one Ga(1) and three equivalent Pb(1) atoms. In the third S site, S(2) is bonded in a water-like geometry to one Ga(1), one Pb(1), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
