The material described by KF2 crystallizes in the tetragonal P4_2/mnm space group. K(1) is bonded to six equivalent F(1) atoms to form a mixture of corner and edge-sharing KF6 octahedra. The corner-sharing octahedral tilt angles are 69°. F(1) is bonded in a distorted trigonal planar geometry to three equivalent K(1) atoms. is represented by the CIF card [CIF]
