description: KInAs3H7O13 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.78–3.01 Å. In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six AsO4 tetrahedra. There are a spread of In–O bond distances ranging from 2.15–2.21 Å. There are three inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 51–59°. There are a spread of As–O bond distances ranging from 1.70–1.76 Å. In the second As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 51–58°.

In the third As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 56–57°. There are a spread of As–O bond distances ranging from 1.70–1.77 Å. There are seven inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.61 Å) H–O bond length. 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. In the third H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.67 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.02 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 linear geometry to two O2- atoms. There is one shorter (1.07 Å) and one longer (1.44 Å) H–O bond length. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one As5+ and one H1+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to one As5+ and two H1+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one In3+, and one As5+ atom.
