Metalhyphen;Metal Bonding in Dicobalt Hexacarbonyl Diphenylacetylene

摘要

The nature of the bonding between the two cobalt atoms in dicobalt hexacarbonyl diphenylacetylene is discussed in terms of simple molecularhyphen;orbital theory. It is shown that, in addition to bonding via the pgr; orbitals of the acetylene residue, it is essential to consider direct overlap between the 4porbitals of the cobalt atoms. Master formulas and numerical tables are derived for the integralsS(4psgr;4psgr;),S(4ppgr;4ppgr;).
