Copper(II) chelates of composition CuL2 were synthesized based on 4-aminomethylene derivatives of 5-thiopyrazoles (LH). The complexes were studied by UV, IR, ESR, and EXAFS spectroscopy, magnetochemistry, and X-ray diffraction analysis. The coordination polyhedra in the complexes are pseudotetrahedra or octahedra of the types CuN2S2 or CuN4S2, respectively, which are distorted due to the Jahn-Teller effect. The UV and ESR spectra of copper chelates with a six-coordinate metallocycle formed by the N and S atoms of the azomethine ligand and the nitrogen atom of the quinoline substituent (R) of the C=N-R fragment are most similar to the spectra observed for metals involved in the active centers of natural metalloenzymes ( blue copper proteins).
