Heteroleptic Palladium(II) Complexes with Mixed Thiol- and Sulfide-containing Amino Acids: Self-assembly of Novel Heptanuclear Coordination Oligomers
Treatment of a cyclic tripalladium(II) complex, [Pd-3(D-pen)(3)] (D-H(2)pen: D-penicillamine), with L-methionine (L-Hmet) gave a novel open-chain-type S-bridged heptapalladium(II) complex, [Pd-7(D-pen)(8)(L-met)(2)](4-), besides a monopalladium(II) complex, [Pd(D-pen)(L-met)](-). A similar reaction using S-methyl-L-cysteine (L-Hsmc) instead of L-Hmet produced an analogous heptapalladium(II) complex, [Pd-7(D-pen)(8)(L-smc)(2)](4-).
