Materials Data on CsLa(WO4)2 by Materials Project

CsLa(WO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Cs1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Cs–O bond distances ranging from 3.05–3.55 Å. La3+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.88 Å. W6+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 41°. There are a spread of W–O bond distances ranging from 1.83–2.26 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Cs1+ and two equivalent W6+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, two equivalent La3+, and one W6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Cs1+, one La3+, and two equivalent W6+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one La3+, and one W6+ atom.
