The structure described by K2SbF5 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 7-coordinate geometry to one F(2), one F(4), one F(5), two equivalent F(1), and two equivalent F(3) atoms. In the second K site, K(2) is bonded in a 7-coordinate geometry to one F(1), one F(3), one F(4), two equivalent F(2), and two equivalent F(5) atoms. Sb(1) is bonded in a square pyramidal geometry to one F(1), one F(2), one F(3), one F(4), and one F(5) atom. There are five inequivalent F sites. In the first F site, F(1) is bonded to one K(2), two equivalent K(1), and one Sb(1) atom to form a mixture of face, corner, and edge-sharing FK3Sb trigonal pyramids. In the second F site, F(2) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Sb(1) atom. In the third F site, F(3) is bonded to one K(2), two equivalent K(1), and one Sb(1) atom to form a mixture of distorted face, corner, and edge-sharing FK3Sb trigonal pyramids. In the fourth F site, F(4) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one Sb(1) atom. In the fifth F site, F(5) is bonded in a 4-coordinate geometry to one K(1), two equivalent K(2), and one Sb(1) atom. is represented by the CIF card [CIF]
