    Van der Waals radii of metals from spectroscopic data (1994)
    Springer
    Russian chemical bulletin 43 (1994), S. 1300-1304 
    Details
    ISSN: 1573-9171
    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.

    Dichotomy in the reaction between cinnamyl dithiocarboxylates and tetracyanoethylene with the formation of 7,8-dithiabicyclo[3.2.1]octanes and dithioacyloxycyclopentanes (1995)
    Springer
    Russian chemical bulletin 44 (1995), S. 1735-1739

    ISSN: 1573-9171
    Keywords: cinnamyl dithiocarboxylates ; tetracyanoethylene ; 2,2,3,3-tetracyano7,8-dithiabicyclo[3.2.1]octanes ; 3,3,4,4-tetracyano-1-dithioacyloxycyclopentanes

    Topics: Chemistry and Pharmacology
    Notes: Abstract The reaction of cinnamyl dithiocarboxylates (1) containing electron-donating substituents at the central carbon atom of the dithioester group (R = p-MeOC6H4, EtO, andp-Tol) with tetracyanoethylene affords 2,2,3,3-tetracyano-4-endo-phenyl-7,8-dithiabicyclo[3.2.1]octanes (2) as well as isomeric 3,3,4,4-tetracyano-2-phenyl-trans-1-dithioacyloxycyclopentanes (3). Dithiabicyclooctanes2 rearrange to the corresponding cyclopentanes3 upon thermolysis.

    Van der Waals radii of elements from the data of structural inorganic chemistry (1995)
    Springer
    Russian chemical bulletin 44 (1995), S. 18-23 
    Details
    ISSN: 1573-9171
    Keywords: molecules, anions ; van der Waals radii ; structure ; molar volume ; polarizability
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract 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. The recommended values of van der Waals radii of elements are tabulated.
