Materials Data on LiLa(MoO4)2 by Materials Project
LiLa(MoO4)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with five MoO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.99–2.38 Å. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.85 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent LiO5 square pyramids. There are a spread of Mo–O bond distances ranging from 1.78–1.81 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent LiO5 square pyramids. There are a spread of Mo–O bond distances ranging from 1.77–1.85 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one La3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Li1+, one La3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one La3+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one La3+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one La3+, and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, two equivalent La3+, and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one La3+, and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one La3+, and one Mo6+ atom.
