The material structure described by Sr8CaCu4(ReO8)3 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. Sr(1) is bonded to three equivalent O(2), three equivalent O(3), and six equivalent O(1) atoms to form distorted SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra,  a faceface with one Ca(1)O6 octahedra,  a faceface with one Cu(1)O6 octahedra, faces with three equivalent Re(1)O6 octahedra, and faces with three equivalent Cu(2)O6 octahedra. Ca(1) is bonded to six equivalent O(3) atoms to form CaO6 octahedra that share corners with six equivalent Re(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Re(1) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form ReO6 octahedra that share corners with two equivalent Ca(1)O6 octahedra, corners with four equivalent Cu(2)O6 octahedra, and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to six equivalent O(2) atoms to form CuO6 octahedra that share corners with six equivalent Cu(2)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second Cu site, Cu(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CuO6 octahedra that share corners with two equivalent Cu(1)O6 octahedra, corners with four equivalent Re(1)O6 octahedra, and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(3) is bonded in a linear geometry to four equivalent Sr(1), one Ca(1), and one Re(1) atom. In the second O site, O(1) is bonded in a distorted linear geometry to four equivalent Sr(1), one Re(1), and one Cu(2) atom. In the third O site, O(2) is bonded to four equivalent Sr(1), one Cu(1), and one Cu(2) atom to form a mixture of corner and face-sharing OSr4Cu2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
