Crystal packing efficiency

WebThe packing efficiency is the fraction of the crystal (or unit cell) actually occupied by the atoms. It must always be less than 100% because it is impossible to pack spheres (atoms are usually spherical) without having … WebTo determine the efficiency of packing of a given crystal structure, we use the packing coefficient C K as defined by Kitaigorodsky. Each molecule is assumed to exclude a volume V mol based on the van der Waals’ radii of its constituent atoms. The packing coefficient for a crystal structure with unit cell volume V cell is therefore (5) ...
