Self-organization has been found out in the crystals of the metal complexes (Cu (II), Pd (II) ) with arginine (Arg) or glutamate (Glu) . The [Cu (L-Arg) <SUB>2</SUB>] -X and [Cu (D-Arg) <SUB>2</SUB>] -X (X=isophthalate, pyridine-2, 6-dicarboxylate, pyridine-3, 5-dicarboxylate) revealed infinite right- and left-handed double-helical structures, respectively. The [Cu (Arg) <SUB>2</SUB>] -X (X=SO<SUB>4</SUB><SUP>2-</SUP>) afforded a single-helical structure, and [Cu (Arg) <SUB>2</SUB>] -X (X=terephthalic acid, pyromellitic acid) gave a layer structure. It indicates that self-organizations in these systems are controlled by dianions. The reaction of [Pd (Arg) <SUB>2</SUB>] <SUP>2+</SUP>complex with isophthalate has also been examined in DMSO-d<SUB>6</SUB> by <SUP>1</SUP>H- and <SUP>13</SUP>C-NMR spectroscopies, in which the molecular process of self assembly in the [Cu (L-Arg) <SUB>2</SUB>] -isophthalate system was successfully followed. Furthermore, the [Pd (L-/D-Glu) (H<SUB>2</SUB>O) ] (H<SUB>2</SUB>O) complexes formed infinite left- and right-handed single-helical structures, respectively, which exhibited not only self-organization but also self-recombination.
