MgH8(C2O)2(CH)10 is Indium-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of forty 02329_fluka molecules and four MgH8(C2O)2 clusters.

There are four inequivalent C sites. In the first C site, C(14) is bonded in a distorted trigonal non-coplanar geometry to one H(17), one H(18), and one O(1) atom. The C(14)-H(17) bond length is 1.10 Å. The C(14)-H(18) bond length is 1.10 Å. The C(14)-O(1) bond length is 1.45 Å. In the second C site, C(11) is bonded in a distorted trigonal non-coplanar geometry to one H(11), one H(12), and one O(2) atom. The C(11)-H(11) bond length is 1.10 Å. The C(11)-H(12) bond length is 1.10 Å. The C(11)-O(2) bond length is 1.46 Å. In the third C site, C(12) is bonded in a distorted trigonal non-coplanar geometry to one H(13), one H(14), and one O(2) atom. The C(12)-H(13) bond length is 1.10 Å. The C(12)-H(14) bond length is 1.09 Å. The C(12)-O(2) bond length is 1.45 Å. In the fourth C site, C(13) is bonded in a distorted trigonal non-coplanar geometry to one H(15), one H(16), and one O(1) atom. The C(13)-H(15) bond length is 1.09 Å. The C(13)-H(16) bond length is 1.10 Å. The C(13)-O(1) bond length is 1.45 Å. There are eight inequivalent H sites. In the first H site, H(16) is bonded in a single-bond geometry to one C(13) atom. In the second H site, H(17) is bonded in a single-bond geometry to one C(14) atom. In the third H site, H(18) is bonded in a single-bond geometry to one C(14) atom. In the fourth H site, H(11) is bonded in a single-bond geometry to one C(11) atom. In the fifth H site, H(15) is bonded in a single-bond geometry to one C(13) atom. In the sixth H site, H(12) is bonded in a single-bond geometry to one C(11) atom. In the seventh H site, H(13) is bonded in a single-bond geometry to one C(12) atom. In the eighth H site, H(14) is bonded in a single-bond geometry to one C(12) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mg(1), one C(13), and one C(14) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mg(1), one C(11), and one C(12) atom. Linkers: 3 C1COCCO1. Metal clusters: 1 C1COCCO1.[Mg].[Mg] ,2 [Mg].
