Abstract
A table of additive covalent radii for tetrahedrally coordinated crystals is obtained by simple quantum-mechanical considerations using the bond lengths of the four diamond-type crystals and only two free parameters. The 39 bond lengths so obtained agree with experiment with an rms error of less than 1%. The extension of these considerations to other crystal structures and to molecules is considered. These radii should be useful for estimating lattice distortions produced by isoelectronic impurities.Keywords
