title: Materials Data on K2AsH13O10 by Materials Project

description: K2AsH13O10 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six O2- atoms to form distorted KO6 pentagonal pyramids that share a cornercorner with one AsO4 tetrahedra. There are a spread of K–O bond distances ranging from 2.74–2.99 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.69–3.07 Å. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share a cornercorner with one KO6 pentagonal pyramid. There are a spread of As–O bond distances ranging from 1.70–1.80 Å. There are thirteen 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 1.01 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.66 Å) H–O bond length. In the third 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 fourth 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 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 1.00 Å. In the eighth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the ninth 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 tenth 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 eleventh 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 twelfth 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 thirteenth 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 ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one As5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one As5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one As5+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one As5+ and one H1+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to one K1+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to two K1+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a water-like geometry to two K1+ and two H1+ atoms.
