The crystal structure described by Cr(NO2)2 is Indium-like structured and crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of two Cr(NO2)2 clusters. In one of the Cr(NO2)2 clusters, Cr(1) is bonded in a 5-coordinate geometry to one N(1), one N(2), one O(3), and two equivalent O(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to one Cr(1) and two equivalent O(1) atoms. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one Cr(1) and 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 single-bond geometry to one N(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Cr(1) atom. In one of the Cr(NO2)2 clusters, Cr(2) is bonded in a tetrahedral geometry to one O(5), one O(6), and two equivalent O(4) atoms. There are two inequivalent N sites. In the first N site, N(3) is bonded in a single-bond geometry to one O(5) atom. In the second N site, N(4) is bonded in a single-bond geometry to one O(6) atom. There are three inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one Cr(2) atom. In the second O site, O(5) is bonded in a bent 120 degrees geometry to one Cr(2) and one N(3) atom. In the third O site, O(6) is bonded in a bent 120 degrees geometry to one Cr(2) and one N(4) atom. is represented by the CIF file [CIF]
