The crystal structure described by KMoSbO5 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded to one O(2), two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms to form distorted KO7 pentagonal bipyramids that share corners with five equivalent Mo(1)O4 tetrahedra and edges with three equivalent K(1)O7 pentagonal bipyramids. Mo(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form MoO4 tetrahedra that share corners with five equivalent K(1)O7 pentagonal bipyramids. Sb(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one Mo(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Mo(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Mo(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Mo(1) atom. is represented by the CIF file [CIF]
