The structure described by KGaGeS4 crystallizes in the monoclinic P2_1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one S(1), one S(2), one S(3), one S(4), one S(5), one S(6), one S(7), and one S(8) atom. In the second K site, K(2) is bonded in a 8-coordinate geometry to one S(1), one S(2), one S(3), one S(4), one S(5), one S(6), one S(7), and one S(8) atom. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one S(1), one S(4), one S(7), and one S(8) atom to form GaS4 tetrahedra that share  a cornercorner with one Ga(2)S4 tetrahedra,  a cornercorner with one Ge(2)S4 tetrahedra, and  an edgeedge with one Ge(1)S4 tetrahedra. In the second Ga site, Ga(2) is bonded to one S(2), one S(4), one S(5), and one S(6) atom to form GaS4 tetrahedra that share  a cornercorner with one Ga(1)S4 tetrahedra,  a cornercorner with one Ge(1)S4 tetrahedra, and corners with two equivalent Ge(2)S4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one S(2), one S(3), one S(7), and one S(8) atom to form GeS4 tetrahedra that share  a cornercorner with one Ga(2)S4 tetrahedra,  a cornercorner with one Ge(2)S4 tetrahedra, and  an edgeedge with one Ga(1)S4 tetrahedra. In the second Ge site, Ge(2) is bonded to one S(1), one S(3), one S(5), and one S(6) atom to form GeS4 tetrahedra that share  a cornercorner with one Ga(1)S4 tetrahedra,  a cornercorner with one Ge(1)S4 tetrahedra, and corners with two equivalent Ga(2)S4 tetrahedra. There are eight inequivalent S sites. In the first S site, S(1) is bonded to one K(1), one K(2), one Ga(1), and one Ge(2) atom to form distorted edge-sharing SK2GaGe trigonal pyramids. In the second S site, S(2) is bonded to one K(1), one K(2), one Ga(2), and one Ge(1) atom to form distorted edge-sharing SK2GaGe trigonal pyramids. In the third S site, S(3) is bonded in a 3-coordinate geometry to one K(1), one K(2), one Ge(1), and one Ge(2) atom. In the fourth S site, S(4) is bonded in a 2-coordinate geometry to one K(1), one K(2), one Ga(1), and one Ga(2) atom. In the fifth S site, S(5) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Ga(2), and one Ge(2) atom. In the sixth S site, S(6) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Ga(2), and one Ge(2) atom. In the seventh S site, S(7) is bonded in a 4-coordinate geometry to one K(1), one K(2), one Ga(1), and one Ge(1) atom. In the eighth S site, S(8) is bonded in a distorted rectangular see-saw-like geometry to one K(1), one K(2), one Ga(1), and one Ge(1) atom. is represented by the CIF file [CIF]
