✦ Synopsis

The structure of tetragonal Ni(II), Cu(H) and Pd-(II) complexes with Tyr-Gly-Gly and Gly-Leu-Tyr has been established by absorption spectroscopy, NMR and EPR methods. The aromatic ring interaction with the metal ion has been proposed and it was found to be most effective for Ni(II). In Cu(II) Gly-Leu-Tyr solution the dimer formation occurs at pH 8-10 and the dimer suffers decomposition at pH above 12.

In the complexes with all three metal ions the ligands act as tetradentate at pH up to 1 I and as tridentate in higher pH regions.

## Abstract Amino acids are known to differ in their individual preferences for each of the four positions of the β‐turn conformation formed by tetrapeptide segments. Proline and glycine show relatively high preferences for positions 2 and 3, respectively, of the β‐turn. Using tripeptides of the ty
