(In)3In3(C9O7)2 is Indium-like structured and crystallizes in the cubic I-43m space group. The structure is zero-dimensional and consists of twelve In clusters and two In3(C9O7)2 clusters. In each In cluster, there are two inequivalent In sites. In the first In site, In(2) is bonded in a distorted single-bond geometry to one In(3) atom. The In(2)-In(3) bond length is 0.76 Å. In the second In site, In(3) is bonded in a linear geometry to one In(2) and one In(3) atom. The In(3)-In(3) bond length is 0.49 Å. In each In3(C9O7)2 cluster, In(1) is bonded to one In(1), one O(1), one O(3), one O(5), and one O(6) atom to form a mixture of distorted edge and corner-sharing InInO4 trigonal bipyramids.

There are nine inequivalent C sites. In the first C site, C(1) is bonded in a bent 120 degrees geometry to one C(2) and one C(8) atom. The C(1)-C(2) bond length is 1.44 Å. The C(1)-C(8) bond length is 1.49 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(1), one C(3), and one C(9) atom. The C(2)-C(3) bond length is 1.45 Å. The C(2)-C(9) bond length is 1.21 Å. In the third C site, C(3) is bonded in a water-like geometry to one C(2), one O(2), and one O(4) atom. The C(3)-O(2) bond length is 1.16 Å. The C(3)-O(4) bond length is 1.26 Å. In the fourth C site, C(4) is bonded in a trigonal planar geometry to one C(5) and two equivalent C(6) atoms. The C(4)-C(5) bond length is 1.49 Å. Both C(4)-C(6) bond lengths are 1.42 Å. In the fifth C site, C(5) is bonded in a bent 120 degrees geometry to one C(4) and two equivalent O(3) atoms. Both C(5)-O(3) bond lengths are 1.24 Å. In the sixth C site, C(6) is bonded in a bent 120 degrees geometry to two equivalent C(4) atoms. In the seventh C site, C(7) is bonded in a bent 120 degrees geometry to one C(8) and two equivalent O(1) atoms. The C(7)-C(8) bond length is 1.52 Å. Both C(7)-O(1) bond lengths are 1.26 Å. In the eighth C site, C(8) is bonded in a trigonal planar geometry to one C(7) and two equivalent C(1) atoms. In the ninth C site, C(9) is bonded in a bent 150 degrees geometry to two equivalent C(2) atoms. There are six inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one C(3) atom. In the second O site, O(3) is bonded in a bent 120 degrees geometry to one In(1) and one C(5) atom. In the third O site, O(4) is bonded in a distorted single-bond geometry to one C(3) atom. In the fourth O site, O(1) is bonded in a bent 120 degrees geometry to one In(1) and one C(7) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent In(1) atoms. In the sixth O site, O(6) is bonded in a distorted hexagonal planar geometry to six equivalent In(1) atoms. Linkers: 32 [O]C(=O)c1[c]c(C([O])=O)[c]c(C([O])=O)[c]1.
