The structure described by KSbP2O8 crystallizes in the trigonal R-3 space group. K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Sb(1) is bonded to six equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1) and three equivalent O(2) atoms to form PO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent K(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
