Cu4C24H8O16Cl crystallizes in the cubic Fm-3m space group. Cu(1) is bonded to two equivalent O(1), two equivalent O(2), and one Cl(1) atom to form distorted corner-sharing CuClO4 square pyramids. Both Cu(1)-O(1) bond lengths are 1.94 Å. Both Cu(1)-O(2) bond lengths are 1.93 Å. The Cu(1)-Cl(1) bond length is 2.54 Å. There are six inequivalent C sites. In the first C site, C(2) is bonded in a trigonal planar geometry to one C(1) and two equivalent C(3) atoms. The C(2)-C(1) bond length is 1.50 Å. Both C(2)-C(3) bond lengths are 1.39 Å. In the second C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2) and two equivalent O(1) atoms. Both C(1)-O(1) bond lengths are 1.25 Å. In the third C site, C(6) is bonded in a single-bond geometry to two equivalent C(5) and one H(2) atom. Both C(6)-C(5) bond lengths are 1.39 Å. The C(6)-H(2) bond length is 0.92 Å.
