The material structure described by K2SbF5 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to eight equivalent F(1) atoms. In the second K site, K(2) is bonded in a 5-coordinate geometry to one F(2) and eight equivalent F(1) atoms. Sb(1) is bonded in a distorted square pyramidal geometry to one F(2) and four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Sb(1) atom. In the second F site, F(2) is bonded in a 2-coordinate geometry to one K(2) and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
