Title: Materials Data on K2ZnH12(SO7)2 by Materials Project

Abstract

K2ZnH12(SO7)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one K2ZnH12(SO7)2 sheet oriented in the (1, 0, 0) direction. K1+ is bonded in a 7-coordinate geometry to one H1+ and six O2- atoms. The K–H bond length is 2.93 Å. There are a spread of K–O bond distances ranging from 2.86–3.22 Å. Zn2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are two shorter (1.99 Å) and two longer (2.03 Å) Zn–O bond lengths. There are six 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 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the fourth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.69 Å) H–O bond length. In the fifth H1+ site, H1+ is bonded inmore » a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a distorted single-bond geometry to one K1+ and two O2- atoms. There is one shorter (1.00 Å) and one longer (1.66 Å) H–O bond length. S6+ is bonded in a water-like geometry to two O2- atoms. There is one shorter (1.67 Å) and one longer (1.68 Å) S–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one K1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to two H1+ atoms. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to one Zn2+, one H1+, and one O2- atom. The O–O bond length is 1.47 Å. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one K1+ and two O2- atoms. The O–O bond length is 1.47 Å. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one H1+, and one S6+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one K1+, one Zn2+, one H1+, and one O2- atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+, one H1+, and one S6+ atom.« less
