described recently, are characterized by fits describing an approximately linear relationship between the π-bonding parameters. The indeterminacy of absolute eπ parameter values is a consequence of the high symmetry in these molecules, actual or effective. The relative contributions of π-bonding between different ligands and with respect to different directions all appear compatible with otherwise established
