TY - JOUR A1 - Kaupp, Martin A1 - Stoll, H. A1 - Preuss, H. T1 - Pseudopotential Calculations for Methyl Compounds of Zinc and Magnesium N2 - Pseudopotentials and valence basis sets to be used in calculations for organometallic compounds of zinc and magnesium have been tested in calculations for the M(CH\(_3\))\(_n\) (M = Zn, Mg; n = 1,2) molecules. Valence correlation effects are treated at the SDCI and CEPA levels. The capability of a polarization potential on zinc to account for the valence shell contracting effect of core valence correlation is studied. Properties considered are geometries, force constants, Mulliken populations, ionization potentials, atomization, and binding energies. Differences in bonding between the two dimethyl compounds are discussed.
