Determination ofABcrystal structures from atomic properties

Abstract
We use atomic pseudopotential s-orbital radii and Pauling electronegativity χ to distinguish between four types of crystal structures (ZnS, NaCl, CsCl, and MnP or NiAs) for AB compounds. By relating χ to the s-orbital radii, an even simpler scheme results, indicating the important role of pseudopotential s-orbital radii for structural determination.
