Title: Materials Data on AlAs(H2O3)2 by Materials Project

Abstract

AlAs(H2O3)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four equivalent AsO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.89–1.97 Å. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with four equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 46–49°. There are a spread of As–O bond distances ranging from 1.71–1.73 Å. There are four 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 distorted bent 150 degrees geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.56 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.59 Å) H–O bond length. 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. There aremore » six inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Al3+, one As5+, and one H1+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Al3+, one As5+, and one H1+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Al3+ and one As5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Al3+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Al3+ and one As5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Al3+ and two H1+ atoms.« less
