The crystal structure described by Sr3Co2(O2Cl)2 crystallizes in the monoclinic C2/m space group. There are four inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. In the second Sr site, Sr(2) is bonded in a body-centered cubic geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(4) atoms. In the third Sr site, Sr(3) is bonded in a 9-coordinate geometry to one O(1), one O(2), two equivalent O(3), two equivalent Cl(2), and three equivalent Cl(1) atoms. In the fourth Sr site, Sr(4) is bonded in a 9-coordinate geometry to one O(1), one O(2), two equivalent O(4), two equivalent Cl(1), and three equivalent Cl(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(3), one O(4), two equivalent O(1), and one Cl(1) atom to form corner-sharing CoClO4 square pyramids. In the second Co site, Co(2) is bonded in a distorted rectangular see-saw-like geometry to one O(3), one O(4), two equivalent O(2), and one Cl(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Sr(1), one Sr(2), one Sr(3), one Sr(4), and two equivalent Co(1) atoms to form a mixture of corner, edge, and face-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-66°. In the second O site, O(2) is bonded to one Sr(1), one Sr(2), one Sr(3), one Sr(4), and two equivalent Co(2) atoms to form a mixture of corner, edge, and face-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-64°. In the third O site, O(3) is bonded to two equivalent Sr(1), two equivalent Sr(3), one Co(1), and one Co(2) atom to form a mixture of distorted corner, edge, and face-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-66°. In the fourth O site, O(4) is bonded to two equivalent Sr(2), two equivalent Sr(4), one Co(1), and one Co(2) atom to form a mixture of distorted corner, edge, and face-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-65°. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 6-coordinate geometry to two equivalent Sr(4), three equivalent Sr(3), and one Co(1) atom. In the second Cl site, Cl(2) is bonded in a distorted hexagonal planar geometry to two equivalent Sr(3), three equivalent Sr(4), and one Co(2) atom. is represented by the CIF file [CIF]
