Materials Data on KLu(MoO4)2 by Materials Project

KLu(MoO4)2 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.71–2.91 Å. Lu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Lu–O bond distances ranging from 2.25–2.51 Å. Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.75–1.87 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Lu3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Lu3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent K1+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Lu3+ and one Mo6+ atom.

Materials Data on KLu(MoO4)2 by Materials Project

KLu(MoO4)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. K1+ is bonded to twelve O2- atoms to form distorted KO12 cuboctahedra that share edges with six equivalent KO12 cuboctahedra, edges with six equivalent MoO4 tetrahedra, and faces with two equivalent LuO6 octahedra. There are six shorter (3.17 Å) and six longer (3.48 Å) K–O bond lengths. Lu3+ is bonded to six equivalent O2- atoms to form LuO6 octahedra that share corners with six equivalent MoO4 tetrahedra and faces with two equivalent KO12 cuboctahedra. All Lu–O bond lengths are 2.19 Å. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent LuO6 octahedra and edges with three equivalent KO12 cuboctahedra. The corner-sharing octahedral tilt angles are 19°. There is one shorter (1.75 Å) and three longer (1.81 Å) Mo–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Lu3+, and one Mo6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to three equivalent K1+ and one Mo6+ atom.
