The structure described by Co2(GeS)3 crystallizes in the monoclinic C2/m space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Ge(2), two equivalent S(1), and two equivalent S(2) atoms to form CoGe2S4 octahedra that share corners with two equivalent Co(1)Ge2S4 octahedra, corners with four equivalent Co(2)Ge4S2 octahedra, and corners with four equivalent Ge(1)Co2S2 tetrahedra. The corner-sharing octahedral tilt angles range from 49-60°. In the second Co site, Co(2) is bonded to two equivalent Ge(1), two equivalent Ge(2), and two equivalent S(1) atoms to form CoGe4S2 octahedra that share corners with two equivalent Co(2)Ge4S2 octahedra, corners with four equivalent Co(1)Ge2S4 octahedra, and corners with four equivalent S(2)Co2Ge2 tetrahedra. The corner-sharing octahedral tilt angles range from 49-63°. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to two equivalent Co(2) and two equivalent S(2) atoms to form GeCo2S2 tetrahedra that share corners with four equivalent Co(1)Ge2S4 octahedra, corners with two equivalent Ge(1)Co2S2 tetrahedra, and  an edgeedge with one Ge(1)Co2S2 tetrahedra. The corner-sharing octahedral tilt angles range from 67-72°. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), and two equivalent Ge(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one Co(2) atom. In the second S site, S(2) is bonded to two equivalent Co(1) and two equivalent Ge(1) atoms to form SCo2Ge2 tetrahedra that share corners with four equivalent Co(2)Ge4S2 octahedra, corners with two equivalent S(2)Co2Ge2 tetrahedra, and  an edgeedge with one S(2)Co2Ge2 tetrahedra.
