In9C13In3C4 is Indium-like structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three In3C4 clusters and three In9C13 clusters. In each In3C4 cluster, In(2) is bonded in a bent 150 degrees geometry to one C(3) and one C(5) atom. The In(2)-C(3) bond length is 1.62 Å. The In(2)-C(5) bond length is 1.13 Å. There are two inequivalent C sites. In the first C site, C(5) is bonded in a trigonal non-coplanar geometry to three equivalent In(2) atoms. In the second C site, C(3) is bonded in a single-bond geometry to one In(2) atom. In each In9C13 cluster, there are two inequivalent In sites. In the first In site, In(1) is bonded in a 3-coordinate geometry to one C(1), one C(2), and one C(4) atom. The In(1)-C(1) bond length is 2.31 Å. The In(1)-C(2) bond length is 1.11 Å. The In(1)-C(4) bond length is 1.15 Å. In the second In site, In(3) is bonded in a 3-coordinate geometry to one C(6) and two equivalent C(2) atoms. The In(3)-C(6) bond length is 1.43 Å. Both In(3)-C(2) bond lengths are 1.57 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a single-bond geometry to one In(1) atom. In the second C site, C(2) is bonded in a 5-coordinate geometry to two equivalent In(1), two equivalent In(3), and one C(4) atom. The C(2)-C(4) bond length is 0.76 Å. In the third C site, C(4) is bonded in a distorted single-bond geometry to two equivalent In(1) and one C(2) atom. In the fourth C site, C(6) is bonded in a 3-coordinate geometry to three equivalent In(3) atoms.
