摘要
The formation constants of the mixed ligand complexes of the type (CuAL), where A refers to glycylglycine (A1), glycyl-l-alanine (A2), and glycyl-l-leucine (A3) and L refers to α-alanine (L1), phenylalanine (L2), tryptophan (L3), tyrosine (L4), and l-dopa (L5), were determined in 1:1 (v/v) dioxan-water medium at 30°C and I = 0.2 M (NaClO4) using an SCOGS computer program. The influence of the noncoordinated aromatic side groups of the amino acids on ternary complex formation is discussed. © 1990.
