Materials Data on Co2N15O11 by Materials Project
(CoN2O3)2(N2)5NO3O2 crystallizes in the tetragonal P4_2nm space group. The structure is zero-dimensional and consists of four ammonia molecules, two hydrogen peroxide molecules, two nitric acid molecules, eight nitrogen molecules, and four CoN2O3 clusters. In each CoN2O3 cluster, Co+2.50+ is bonded in a distorted water-like geometry to one N+1.13+ and one O2- atom. The Co–N bond length is 1.83 Å. The Co–O bond length is 1.92 Å. There are two inequivalent N+1.13+ sites. In the first N+1.13+ site, N+1.13+ is bonded in a linear geometry to one Co+2.50+ and one O2- atom. The N–O bond length is 1.16 Å. In the second N+1.13+ site, N+1.13+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.23 Å) and one longer (1.32 Å) N–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N+1.13+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Co+2.50+ and one N+1.13+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one N+1.13+ atom.
