description: Zn(NO3)4(NH4)2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of eight ammonium molecules and four Zn(NO3)4 clusters. In two of the Zn(NO3)4 clusters, Zn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Zn–O bond distances ranging from 2.06–2.36 Å. There are four inequivalent N+2.33+ sites. In the first N+2.33+ site, N+2.33+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.25–1.30 Å. In the second N+2.33+ site, N+2.33+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.29 Å. In the third N+2.33+ site, N+2.33+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.23–1.30 Å. In the fourth N+2.33+ site, N+2.33+ is bonded in a trigonal planar geometry to three O2- atoms.
