MnH4(C2O)4(C5H2)2 is Indium-derived structured and crystallizes in the cubic Im-3m space group. The structure is zero-dimensional and consists of sixteen 1,3,5-triisopropenyl benzene molecules and six MnH4(C2O)4 clusters. In each MnH4(C2O)4 cluster, Mn(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. All Mn(1)-O(1) bond lengths are 2.10 Å. There are three inequivalent C sites. In the first C site, C(3) is bonded in a trigonal planar geometry to one C(4) and two equivalent C(1) atoms. The C(3)-C(4) bond length is 1.49 Å. Both C(3)-C(1) bond lengths are 1.38 Å. In the second C site, C(4) is bonded in a distorted bent 120 degrees geometry to one C(3) and two equivalent O(1) atoms. Both C(4)-O(1) bond lengths are 1.23 Å. In the third C site, C(1) is bonded in a single-bond geometry to one C(3) and one H(1) atom. The C(1)-H(1) bond length is 0.93 Å. H(1) is bonded in a single-bond geometry to one C(1) atom. O(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one C(4) atom. Linkers: 16 [O]C(=O)c1ccc(-c2[c]c(-c3ccc(C([O])=O)cc3)[c]c(-c3ccc(C([O])=O)cc3)[c]2)cc1.
