Materials Data on K2Zn(H2N)4 by Materials Project
K2Zn(NH2)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six N3- and seven H1+ atoms. There are a spread of K–N bond distances ranging from 2.84–3.08 Å. There are a spread of K–H bond distances ranging from 2.73–3.10 Å. In the second K1+ site, K1+ is bonded in a 1-coordinate geometry to five N3- and two H1+ atoms. There are a spread of K–N bond distances ranging from 2.85–3.04 Å. There are one shorter (2.82 Å) and one longer (2.99 Å) K–H bond lengths. Zn2+ is bonded in a tetrahedral geometry to four N3- atoms. There are a spread of Zn–N bond distances ranging from 2.07–2.09 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted water-like geometry to three K1+, one Zn2+, and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the second N3- site, N3- is bonded in a distorted water-like geometry to three K1+, one Zn2+, and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the third N3- site, N3- is bonded in a distorted water-like geometry to three K1+, one Zn2+, and two H1+ atoms. Both N–H bond lengths are 1.03 Å. In the fourth N3- site, N3- is bonded in a distorted water-like geometry to two K1+, one Zn2+, and two H1+ atoms. Both N–H bond lengths are 1.03 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two equivalent K1+ and one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one N3- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one N3- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one N3- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one N3- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one N3- atom.
