KInF3 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent F(1) atoms to form distorted KF12 cuboctahedra that share corners with twelve equivalent K(1)F12 cuboctahedra, faces with six equivalent K(1)F12 cuboctahedra, faces with four equivalent In(1)F6 octahedra, and faces with four equivalent In(2)F6 octahedra. There are two inequivalent In sites. In the first In site, In(1) is bonded to six equivalent F(1) atoms to form InF6 octahedra that share corners with six equivalent In(2)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second In site, In(2) is bonded to six equivalent F(1) atoms to form InF6 octahedra that share corners with six equivalent In(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent K(1), one In(1), and one In(2) atom.
