CoN5Cl2NO2 is alpha Niobium phosphide structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four nitrous acid molecules and four CoN5Cl2 clusters. In each CoN5Cl2 cluster, Co2+ is bonded in a single-bond geometry to three N+0.67+ atoms. There is one shorter (1.59 Å) and two longer (1.95 Å) Co–N bond length. There are three inequivalent N+0.67+ sites. In the first N+0.67+ site, N+0.67+ is bonded in a single-bond geometry to one Cl1- atom. The N–Cl bond length is 1.51 Å. In the second N+0.67+ site, N+0.67+ is bonded in a 2-coordinate geometry to one Co2+ and one Cl1- atom. The N–Cl bond length is 1.53 Å. In the third N+0.67+ site, N+0.67+ is bonded in a single-bond geometry to one Co2+ atom. Cl1- is bonded in a bent 120 degrees geometry to two N+0.67+ atoms.
