While a large number of polynuclear and supramolecular compounds have been synthesized via self-assembly of well-designed organic ligands with transition metal ions, our synthetic strategy of this class of compounds has been directed toward the use of metal complexes with simple aliphatic thiols, such as 2-aminoethanethiol, L-cysteine, and D-penicillamine (D-H2pen), as functional metalloligands. In this seminar, I will present the rational construction of a variety of chiral coordination compounds based on the two-coordinate aurate(I) metalloligand with D-penicillamine, which possesses noncoordinating amine and carboxylate groups as potential coordination sites, besides thiolato donor groups. Another metalloligand system will also be presented.
