CO(NH2)2 crystallizes in the tetragonal P4_12_12 space group. The structure is zero-dimensional and consists of four CO(NH2)2 clusters. there are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.27 Å) and two longer (1.32 Å) C–O bond length. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three N3- atoms. There are a spread of C–N bond distances ranging from 1.28–1.51 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. In the second N3- site, N3- is bonded in a distorted tetrahedral geometry to one C4+ and three H1+ atoms. There is two shorter (1.03 Å) and one longer (1.12 Å) N–H bond length. In the third N3- site, N3- is bonded in a bent 120 degrees geometry to one C4+ and one H1+ atom. The N–H bond length is 1.03 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the sixth H1+ site, H1+ is bonded in a linear geometry to one N3- and one O2- atom. The H–O bond length is 1.46 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C4+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one C4+ and one H1+ atom.
