One of the fluoride ions releases an electron and moves into one of the empty cubes. A covalent bond is established to one of the neighboring fluorides on a regular lattice site, thus a H-center (F 2-, see below) is formed. The electron localizes on the vacant lattice site to form a F-center. heri to car in michigan
