Title: Materials Data on Al2Si2PbO8 by Materials Project

Abstract

PbAl2Si2O8 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four SiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.74–1.79 Å. In the second Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four SiO4 tetrahedra. There is two shorter (1.74 Å) and two longer (1.78 Å) Al–O bond length. In the third Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four SiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.75–1.77 Å.

In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Al3+, one Pb2+, and one Si4+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+, one Pb2+, and one Si4+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Al3+, one Pb2+, and one Si4+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Al3+, one Pb2+, and one Si4+ atom. In the eleventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Al3+ and one Si4+ atom. In the twelfth O2- site, O2- is bonded in a bent 120 degrees geometry to one Al3+ and one Si4+ atom.
