FeI(NO)2 is Indium-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four FeI(NO)2 clusters. Fe(1) is bonded to one N(1), one N(2), and two equivalent I(1) atoms to form distorted edge-sharing FeI2N2 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to one Fe(1) and one O(1) atom. In the second N site, N(2) is bonded in a linear geometry to one Fe(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one N(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one N(2) atom. I(1) is bonded in a distorted L-shaped geometry to two equivalent Fe(1) atoms.

Fe(1) is bonded to one N(1), one N(2), and two equivalent I(1) atoms to form distorted edge-sharing FeI2N2 tetrahedra. The Fe(1)-N(1) bond length is 1.79 Å. The Fe(1)-N(2) bond length is 1.79 Å. There is one shorter (2.71 Å) and one longer (2.72 Å) Fe(1)-I(1) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 150 degrees geometry to one Fe(1) and one O(1) atom. The N(1)-O(1) bond length is 1.19 Å.
