Materials Data on KLa(WO4)2 by Materials Project
KLa(WO4)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.63–3.05 Å. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.46–2.65 Å. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form distorted edge-sharing WO6 octahedra. There are a spread of W–O bond distances ranging from 1.83–2.15 Å. In the second W6+ site, W6+ is bonded to six O2- atoms to form distorted edge-sharing WO6 octahedra. There are a spread of W–O bond distances ranging from 1.82–2.19 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one K1+, one La3+, and two W6+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, one La3+, and one W6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one La3+, and one W6+ atom. In the fourth O2- site, O2- is bonded to one K1+ and three W6+ atoms to form distorted edge-sharing OKW3 tetrahedra. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one K1+, two equivalent La3+, and one W6+ atom.
