Sr4C40H8S8O17 crystallizes in the cubic Fm-3c space group. Sr(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(1), and four equivalent O(2) atoms. The Sr(1)-O(3) bond length is 2.65 Å. Both Sr(1)-O(1) bond lengths are 2.66 Å. There are two shorter (2.46 Å) and two longer (2.64 Å) Sr(1)-O(2) bond lengths. There are five inequivalent C sites. In the first C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one S(1) atom. The C(2)-C(1) bond length is 1.48 Å. The C(2)-C(3) bond length is 1.40 Å. The C(2)-S(1) bond length is 1.73 Å. In the second C site, C(1) is bonded in a bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-O(1) bond length is 1.25 Å. The C(1)-O(2) bond length is 1.26 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2), one C(5), and one H(1) atom. The C(3)-C(5) bond length is 1.44 Å. The C(3)-H(1) bond length is 0.93 Å. In the fourth C site, C(4) is bonded in a trigonal planar geometry to two equivalent C(5) and one S(1) atom.
