Abstract

KEu(WO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.86–3.12 Å. Eu3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Eu–O bond distances ranging from 2.36–2.39 Å. W6+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 40°. There are a spread of W–O bond distances ranging from 1.83–2.13 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Eu3+, and one W6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+ and two equivalent W6+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one K1+, one Eu3+, and two equivalent W6+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Eu3+, and one W6+ atom.
