The compound described by Cr(NO2)2 is Indium-like structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four Cr(NO2)2 clusters. Cr(1) is bonded in a 5-coordinate geometry to one N(1), one O(1), one O(2), and two equivalent O(3) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to one Cr(1) and one O(1) atom. In the second N site, N(2) is bonded in a single-bond geometry to one O(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Cr(1) and one N(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cr(1) and one N(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Cr(1) atom. is represented by the CIF file [CIF]
