The (2-aminoethyl)phosphine ligand has the structure shown below; it often acts as a bidentate ligand toward transition metals. (See N. Komine, S. Tsutsuminai, M. Hirano, S. Komiya, J. Organomet. Chem. , 2007 , 692 , 4486.)
a. When this ligand forms monodentate complexes with palladium, it bonds through its phosphorus atom rather than its nitrogen. Suggest an explanation.
b. How many possible isomers of dichlorobis [(2-aminoethyl) phosphine]nickel(II), an octahedral coordination complex in which (2-aminoethyl)phosphine is bidentate, are there? Sketch each isomer, and identify any pairs of enantiomers.
c. Classify the configuration of chiral isomers as
