    Topics: Chemistry and Pharmacology
    Notes: Abstract The anisotropic components of van der Waals radii for 5b, 6b and 7b Group elements were determined from the structures of gaseous van der Waals complexes and of crystalline molecular solids. The transition from the gaseous to the solid state reduces the anisotropy of a van der Waals atomic shape. This anisotropy is largely responsible for the changes of intermolecular distances, which are often misinterpreted as an effect of hydrogen bonds.

    Keywords: van der Waals molecules ; van der Waals radii of metals ; polarizability ; dissociation energy ; interatomic distances
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The lack of information about the van der Waals radii of metals can be compensated for by using the results of spectroscopic investigations of van der Waals molecules. It has been shown that the interatomic distances in these molecules obey an additive scheme if one allows for the polarization effects. The van der Waals radii of the alkali metals, Ag, Mg, Zn, Cd, Hg, B, Al, In, and Si, have been determined from the interatomic distances in their heteroatomic molecules with atoms of noble gases. Use of the obtained radii for crystal chemistry is discussed.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The results of direct experimental determination of covalent bond lengths in molecular structures are presented. This made it possible to establish the values of normal covalent radii. The recommended values of covalent radii for 56 elements are tabulated.
