Materials Data on NaZn(H3O2)3 by Materials Project
NaZn(H3O2)3 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two NaZn(H3O2)3 ribbons oriented in the (1, 0, 0) direction. Na1+ is bonded in a 6-coordinate geometry to one H1+ and six O2- atoms. The Na–H bond length is 2.48 Å. There are a spread of Na–O bond distances ranging from 2.34–2.57 Å. Zn2+ is bonded to four O2- atoms to form corner-sharing ZnO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 2.00–2.02 Å. There are nine 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 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third 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 fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one Na1+ and one O2- atom. The H–O bond length is 0.98 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one Na1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+, two equivalent Zn2+, and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Zn2+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Zn2+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Na1+ and two H1+ atoms.
