InC16(NO)8 crystallizes in the hexagonal P6_222 space group. In(1) is bonded in a distorted hexagonal bipyramidal geometry to four equivalent O(1) and four equivalent O(2) atoms. All In(1)-O(1) bond lengths are 2.25 Å. All In(1)-O(2) bond lengths are 2.28 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.46 Å. The C(1)-O(1) bond length is 1.25 Å. The C(1)-O(2) bond length is 1.26 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(4) atom. The C(2)-C(3) bond length is 1.41 Å. The C(2)-C(4) 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 N(2) atom. The C(3)-N(2) bond length is 1.42 Å. In the fourth C site, C(4) is bonded in a distorted trigonal planar geometry to one C(2), one C(4), and one N(1) atom. The C(4)-C(4) bond length is 1.45 Å. The C(4)-N(1) bond length is 1.42 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a single-bond geometry to one C(4) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to one C(3) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in an L-shaped geometry to one In(1) and one C(1) atom. In the second O site, O(2) is bonded in an L-shaped geometry to one In(1) and one C(1) atom.
