KSbO3 crystallizes in the triclinic P-1 space group. K(1) is bonded in a 7-coordinate geometry to two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. Sb(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form edge-sharing SbO5 square pyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent K(1) and two equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing OK3Sb2 trigonal bipyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to two equivalent K(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent K(1), one Sb(1), and one O(3) atom.
