Materials Data on Al2(SeO4)3 by Materials Project
Al2(SeO4)3 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with six SeO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.88–1.92 Å. There are two inequivalent Se6+ sites. In the first Se6+ site, Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with four equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 15–40°. There is two shorter (1.64 Å) and two longer (1.67 Å) Se–O bond length. In the second Se6+ site, Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with four equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 9–44°. There are a spread of Se–O bond distances ranging from 1.65–1.67 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Al3+ and one Se6+ atom. In the second O2- site, O2- is bonded in a linear geometry to one Al3+ and one Se6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Al3+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one Se6+ atom.
