An organometallic complex that mimics an aminoacid, also known as an aminoacidisostere, can be synthesized from a functionalized bipyridine ligand and a fac-[Re(CO)3]+ center. The reaction of an achiral ligand and metal results in a racemic mixture of chiral-at-metal complexes. These metal species have amine and carboxy termini, a side chain type unit that can be varied, as well as the chiral metal

The metal coordinating ability of a bipyridine ligand at the core of a peptide dendrimer was found to be controlled by the nature of amino acids placed at the dendrimer periphery, with coordination being promoted by anionic residues and inhibited by cationic residues; heterotrimers with mixed charges were preferentially formed.
