Materials Data on KSb(PO4)2 by Materials Project
KSbP2O8 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All K–O bond lengths are 2.99 Å. Sb5+ is bonded to six equivalent O2- atoms to form SbO6 octahedra that share corners with six equivalent PO4 tetrahedra. All Sb–O bond lengths are 1.99 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent SbO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There is one shorter (1.49 Å) and three longer (1.58 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent K1+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb5+ and one P5+ atom.
