The compound described by Li2Co2(SO4)3 crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(4), and two equivalent O(2) atoms. Co(1) is bonded to one O(1), one O(3), one O(5), one O(6), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with two equivalent S(2)O4 tetrahedra, corners with four equivalent S(1)O4 tetrahedra, and  an edgeedge with one Co(1)O6 octahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form SO4 tetrahedra that share corners with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-54°. In the second S site, S(2) is bonded to two equivalent O(1) and two equivalent O(5) atoms to form SO4 tetrahedra that share corners with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 17-34°. There are six inequivalent O sites. In the first O site, O(4) is bonded to one Li(1), two equivalent Co(1), and one S(1) atom to form distorted edge-sharing OLiCo2S trigonal pyramids. In the second O site, O(5) is bonded in a distorted linear geometry to one Co(1) and one S(2) atom. In the third O site, O(6) is bonded in a bent 150 degrees geometry to one Co(1) and one S(1) atom. In the fourth O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one Co(1), and one S(2) atom. In the fifth O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one S(1) atom. In the sixth O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1), one Co(1), and one S(1) atom. is represented by the CIF file [CIF]
