MnC10H2(SO2)2 crystallizes in the cubic Fm-3c space group. Mn(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. Both Mn(1)-O(1) bond lengths are 2.19 Å. There are two shorter (2.13 Å) and two longer (2.64 Å) Mn(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 1.44 Å. The C(2)-S(1) bond length is 1.74 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 1.26 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(4), and one H(1) atom. The C(3)-C(4) bond length is 1.47 Å. The C(3)-H(1) bond length is 0.95 Å. In the fourth C site, C(4) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(5) atoms. Both C(4)-C(5) bond lengths are 1.41 Å. In the fifth C site, C(5) is bonded in a trigonal planar geometry to two equivalent C(4) and one S(1) atom. The C(5)-S(1) bond length is 1.71 Å. H(1) is bonded in a single-bond geometry to one C(3) atom. S(1) is bonded in an L-shaped geometry to one C(2) and one C(5) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Mn(1) and one C(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent Mn(1) and one C(1) atom.
