Question

Van der waals radii of elements from structural inorganic chemistry data

Answer 1

 The recommended values of van der Waals radii of elements are tabulated. Key words: molecules, anions; van der Waals radii; structure; molar volume; polarizability. The known systems of van der Waals radii 1-7 were created mainly on the basis of data of structural organic chemistry.

Van der Waals radii of elements were determined from the data of the structural inorganic chemistry: from intersitial distances in CdX2- and graphite-type structures, bond lengths in van der Waals molecules, molar volumes of A2-type substances, refractometry data, and from quantum chemical and correlation ratios.
