Materials Data on Zn(NO4)2 by Materials Project

Zn(NO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one Zn(NO4)2 sheet oriented in the (1, 0, 0) direction. Zn is bonded in an octahedral geometry to six O atoms. There are a spread of Zn–O bond distances ranging from 1.97–2.33 Å. N is bonded in a trigonal planar geometry to three O atoms. There are a spread of N–O bond distances ranging from 1.23–1.30 Å. There are four inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one Zn and one N atom. In the second O site, O is bonded in a single-bond geometry to one N atom. In the third O site, O is bonded in a bent 120 degrees geometry to one Zn and one N atom. In the fourth O site, O is bonded in a single-bond geometry to one Zn atom.

Materials Data on ZnH4(NO4)2 by Materials Project

ZnH4(NO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one ZnH4(NO4)2 sheet oriented in the (1, 0, 0) direction. Zn2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Zn–O bond distances ranging from 2.05–2.25 Å. N5+ 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. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one N5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one N5+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Zn2+ and two H1+ atoms.
