Materials Data on LaSO5 by Materials Project
LaSO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of La–O bond distances ranging from 2.45–2.78 Å. S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.46–1.52 Å. There are five inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one La and one S atom. In the second O site, O is bonded in a trigonal non-coplanar geometry to three equivalent La atoms. In the third O site, O is bonded in a distorted bent 150 degrees geometry to one La and one S atom. In the fourth O site, O is bonded in a distorted trigonal planar geometry to two equivalent La and one S atom. In the fifth O site, O is bonded in a single-bond geometry to two equivalent La and one S atom.
