The material described by KLaF4 is Fluorite-derived structured and crystallizes in the tetragonal P4/mmm space group. K(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. La(1) is bonded in a body-centered cubic geometry to eight equivalent F(1) atoms. F(1) is bonded to two equivalent K(1) and two equivalent La(1) atoms to form a mixture of corner and edge-sharing FK2La2 tetrahedra. is represented by the CIF card [CIF]
