The crystal structure described by Sr8Co6O15Cl4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted q6 geometry to one O(2); one O(3); one O(4); one O(5); one O(6); two equivalent O(7,8); and four equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded in a 9-coordinate geometry to one O(2), one O(3), one O(4), one O(5), and five equivalent Cl(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one Cl(1) atom to form CoClO5 square pyramids that share  a cornercorner with one Co(2)O5 square pyramid and corners with four equivalent Co(1)ClO5 square pyramids. In the second Co site, Co(2) is bonded to one O(6); two equivalent O(1); and two equivalent O(7,8) atoms to form CoO5 square pyramids that share corners with two equivalent Co(1)ClO5 square pyramids and corners with three equivalent Co(2)O5 square pyramids. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one Co(1), and one Co(2) atom. In the second O site, O(2) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Co(1) atoms to form a mixture of distorted corner and face-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles are 58°. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Co(1) atoms. In the fourth O site, O(4) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Co(1) atoms to form a mixture of distorted corner, face, and edge-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 2-14°. In the fifth O site, O(5) is bonded to two equivalent Sr(1), two equivalent Sr(2), and two equivalent Co(1) atoms to form a mixture of distorted corner, face, and edge-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 2-14°. In the sixth O site, O(6) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Co(2) atoms. In the seventh O site, O(7,8) is bonded to four equivalent Sr(1) and two equivalent Co(2) atoms to form a mixture of distorted corner and edge-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles range from 2-58°. Cl(1) is bonded in a 6-coordinate geometry to five equivalent Sr(2) and one Co(1) atom. is represented by the CIF card [CIF]
