The crystal structure described by K3SbO4 crystallizes in the monoclinic P2/c space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a distorted bent 150 degrees geometry to two equivalent O(1) and four equivalent O(2) atoms. In the second K site, K(2) is bonded in a distorted hexagonal planar geometry to two equivalent O(1) and four equivalent O(2) atoms. In the third K site, K(3) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing SbO6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one K(1), one K(2), two equivalent K(3), and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a 6-coordinate geometry to one K(3), two equivalent K(1), two equivalent K(2), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
