Materials Data on Co2N16O9 by Materials Project
Co2N5(N2)4(NO3)3 crystallizes in the tetragonal P4_2nm space group. The structure is zero-dimensional and consists of four ammonia molecules, six nitric acid molecules, four triazane molecules, and two Co2N5 clusters. In each Co2N5 cluster, Co2+ is bonded in a trigonal planar geometry to three N+0.88+ atoms. There is two shorter (1.59 Å) and one longer (1.67 Å) Co–N bond length. There are two inequivalent N+0.88+ sites. In the first N+0.88+ site, N+0.88+ is bonded in a bent 150 degrees geometry to two equivalent Co2+ atoms. In the second N+0.88+ site, N+0.88+ is bonded in a single-bond geometry to one Co2+ atom.
