CORRELATION ANALYSIS OF THE INFLUENCE OF SUBSTITUENTS ON THE DENSITY OF ORGANOMETALLIC COMPOUNDS

Literature data on the density of 25 series of boron, aluminum, silicon, germanium, tin, lead, phosphorus, and arsenic compounds forming weak intermolecular complexes have been analyzed using the correlation-analysis method. During the formulation of a weak complex, an excess charge appears at the reactive site of such a compound, which in turn induces a dipole in the substituent of the compound, with the result that the ion–dipole interaction (polarization eff ect) occurs. It was shown for the fi rst time that the density of the indicated compounds depends not only on the classical inductive, resonance, and steric eff ects of the substituents, but also on the polarization eff ect whose contribution may amount to as much as 54%.
