Abstract

K3Lu(PO4)2 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 1-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.66–3.23 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.80 Å) and three longer (2.93 Å) K–O bond lengths. In the third K1+ site, K1+ is bonded to twelve O2- atoms to form KO12 cuboctahedra that share edges with six equivalent PO4 tetrahedra and faces with two equivalent LuO6 octahedra. There are six shorter (3.16 Å) and six longer (3.36 Å) K–O bond lengths. There are two inequivalent Lu3+ sites. In the first Lu3+ site, Lu3+ is bonded to six O2- atoms to form LuO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are three shorter (2.18 Å) and three longer (2.23 Å) Lu–O bond lengths. In the second Lu3+ site, Lu3+ is bonded to six equivalent O2- atoms to form LuO6 octahedra that share corners with six equivalent PO4 tetrahedra and faces with two equivalent KO12 cuboctahedra.
