In3H6(C9O8)2 crystallizes in the trigonal R32 space group. In(1) is bonded to one O(4), two equivalent O(1), and two equivalent O(2) atoms to form corner-sharing InO5 square pyramids. The In(1)-O(4) bond length is 2.04 Å. Both In(1)-O(1) bond lengths are 2.17 Å. Both In(1)-O(2) bond lengths are 2.15 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.50 Å. The C(1)-O(1) bond length is 1.28 Å. The C(1)-O(2) bond length is 1.24 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one C(3), and one O(3) atom. The C(2)-C(3) bond length is 1.30 Å. The C(2)-O(3) bond length is 1.39 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(3)-H(1) bond length is 0.93 Å. H(1) is bonded in a single-bond geometry to one C(3) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a trigonal planar geometry to three equivalent In(1) atoms. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one In(1) and one C(1) atom. In the third O site, O(2) is bonded in a 2-coordinate geometry to one In(1) and one C(1) atom. In the fourth O site, O(3) is bonded in a water-like geometry to two equivalent C(2) atoms. Linkers: 9 [O]C(=O)c1ccc(C([O])=O)o1.
