Materials Data on SrLa2WO7 by Materials Project
SrLa2WO7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.53–3.20 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.38–2.95 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.36–2.77 Å. W6+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 1.93–2.01 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Sr2+, two La3+, and one W6+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, two La3+, and one W6+ atom. In the third O2- site, O2- is bonded to four La3+ atoms to form edge-sharing OLa4 tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Sr2+, one La3+, and one W6+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to three La3+ and one W6+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sr2+, two La3+, and one W6+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, two La3+, and one W6+ atom.
