Аннотация:Complex [Cu(H2L)2(Н2О)2] has been obtained by the reaction of copper(II) with 2-hydroxy-5-ethylphenylphosphonic acid (H3L), and its structure was studied by X-ray diffraction. Protonation constants of acid H3L and stability constants of its complexes with Cu2+ in water have been determined by potentiometric titration. Complex [Cu(H2L)2(Н2О)2] has been found to show low toxicity and high analgesic activity.
