various metal complexes of diphenylphosphinophenylacetylene can be used as indicators of the relative amounts of retrodative π-bonding from filled metal d orbitals to the empty phosphorus d orbitals of the phosphine ligand. Using this frequency as an indicator, retrodative π-bonding is shown to be weaker in tetrahedral complexes than in octahedral, trigonal bipyramidal, or square planar complexes.
