Materials Data on Ca2AlH10IO8 by Materials Project
Ca2AlH10O8I crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one Ca2AlH10O8I sheet oriented in the (0, 0, 1) direction. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to seven O2- atoms to form distorted CaO7 pentagonal bipyramids that share edges with three equivalent AlO6 octahedra and edges with three equivalent CaO7 pentagonal bipyramids. There are a spread of Ca–O bond distances ranging from 2.39–2.48 Å. In the second Ca2+ site, Ca2+ is bonded to seven O2- atoms to form distorted CaO7 pentagonal bipyramids that share edges with three equivalent AlO6 octahedra and edges with three equivalent CaO7 pentagonal bipyramids. There are a spread of Ca–O bond distances ranging from 2.39–2.48 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share edges with six CaO7 pentagonal bipyramids. There are a spread of Al–O bond distances ranging from 1.92–1.94 Å. There are ten 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 0.97 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- and one I1- atom. The H–O bond length is 0.99 Å. The H–I bond length is 2.41 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 single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the sixth 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 seventh 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 eighth 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 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. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two Ca2+, one Al3+, and one H1+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Ca2+, one Al3+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Ca2+, one Al3+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Ca2+, one Al3+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two Ca2+, one Al3+, and one H1+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to two Ca2+, one Al3+, and one H1+ atom. In the eighth O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms. I1- is bonded in a single-bond geometry to one H1+ atom.
