InC12H4(NO2)4 is Indium-like structured and crystallizes in the tetragonal I4_1/a space group. The structure is zero-dimensional and consists of four InC12H4(NO2)4 clusters. In(1) is bonded in a 8-coordinate geometry to four equivalent N(1) and four equivalent O(1) atoms. All In(1)-N(1) bond lengths are 2.45 Å. All In(1)-O(1) bond lengths are 2.19 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 N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.34 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one N(1) atom. The C(2)-N(1) bond length is 1.34 Å. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(3)-O(1) bond length is 1.29 Å. The C(3)-O(2) bond length is 1.23 Å. N(1) is bonded in a distorted trigonal planar geometry to one In(1), one C(1), and one C(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one In(1) and one C(3) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(3) atom.
