KSbV2O8 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 11-coordinate geometry to one O(3), two equivalent O(2), two equivalent O(5), two equivalent O(6), and four equivalent O(1) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), and two equivalent O(6) atoms to form VO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-36°. In the second V site, V(2) is bonded to one O(4), one O(5), and two equivalent O(1) atoms to form VO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-42°. Sb(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(6) atoms to form SbO6 octahedra that share corners with three equivalent V(1)O4 tetrahedra and corners with three equivalent V(2)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to two equivalent K(1), one V(2), and one Sb(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent K(1), one V(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one K(1) and one V(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(2) and one Sb(1) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to two equivalent K(1) and one V(2) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one K(1), one V(1), and one Sb(1) atom.
