Mn7C30H6(NO2)12 crystallizes in the cubic Fm-3 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted octahedral geometry to three equivalent N(1) and three equivalent O(1) atoms. All Mn(1)-N(1) bond lengths are 2.14 Å. All Mn(1)-O(1) bond lengths are 2.19 Å. In the second Mn site, Mn(2) is bonded in a square co-planar geometry to four equivalent O(2) atoms. All Mn(2)-O(2) bond lengths are 2.11 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted single-bond geometry to one N(1) atom. The C(1)-N(1) bond length is 1.37 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(2)-O(1) bond length is 1.27 Å. The C(2)-O(2) bond length is 1.25 Å. In the third C site, C(3) is bonded in a trigonal planar geometry to two equivalent N(1) and one H(1) atom. Both C(3)-N(1) bond lengths are 1.33 Å. The C(3)-H(1) bond length is 0.95 Å. N(1) is bonded in a distorted trigonal planar geometry to one Mn(1), one C(1), and one C(3) atom. H(1) is bonded in a single-bond geometry to one C(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Mn(1) and one C(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Mn(2) and one C(2) atom.
