The structure described by K2Na2Sb2H2OF10(H2O)2 crystallizes in the monoclinic P2_1/m space group. The structure consists of four water molecules inside a K2Na2Sb2H2OF10 framework. In the K2Na2Sb2H2OF10 framework, K(1) is bonded in a 10-coordinate geometry to two equivalent F(1), two equivalent F(2), two equivalent F(3), two equivalent F(4), and two equivalent F(5) atoms. Na(1) is bonded to one O(1), one F(1), one F(2), one F(3), one F(4), and one F(5) atom to form distorted NaOF5 octahedra that share  a cornercorner with one Na(1)OF5 octahedra and corners with five equivalent Sb(1)F5 square pyramids. The corner-sharing octahedral tilt angles are 17°. Sb(1) is bonded to one F(1), one F(2), one F(3), one F(4), and one F(5) atom to form distorted SbF5 square pyramids that share corners with five equivalent Na(1)OF5 octahedra. The corner-sharing octahedral tilt angles range from 3-29°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a water-like geometry to two equivalent Na(1), one H(1), and one H(2) atom. There are five inequivalent F sites. In the first F site, F(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent K(1), one Na(1), and one Sb(1) atom. In the second F site, F(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent K(1), one Na(1), and one Sb(1) atom. In the third F site, F(4) is bonded in a distorted see-saw-like geometry to two equivalent K(1), one Na(1), and one Sb(1) atom. In the fourth F site, F(5) is bonded in a distorted linear geometry to two equivalent K(1), one Na(1), and one Sb(1) atom. In the fifth F site, F(1) is bonded in a 4-coordinate geometry to two equivalent K(1), one Na(1), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
