In solid sodium chloride, each ion is surrounded by six ions of the opposite charge as expected on electrostatic grounds. The surrounding ions are located at the vertices of a regular octahedron. In the language of close-packing, the larger chloride ions (167 pm in size ) are arranged in a cubic array whereas the smaller sodium ions (116 pm ) fill all the cubic gaps (octahedral voids) between them.
