The crystal structure described by Sr4Cu3O6Cl crystallizes in the cubic Im-3m space group. Sr(1) is bonded to six equivalent O(1) and two equivalent Cl(1) atoms to form a mixture of face and corner-sharing SrCl2O6 hexagonal bipyramids. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to four equivalent Sr(1) and two equivalent Cu(1) atoms to form a mixture of face and corner-sharing OSr4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. Cl(1) is bonded in a body-centered cubic geometry to eight equivalent Sr(1) atoms. is represented by the CIF card [CIF]
