Abstract
The binding mechanism between Cu(II) ions and bioactive Schiff base derivative ligands, i.e., 2-[(4-methoxyphenylimino)metyl]phenol, 4,6-dichloro-2-[(4-hydroxyphenyl-imino)methyl]phenol and 4,6-dichloro-2-[(4-methoxyphenylimino)methyl]phenol, in the form of non-crystalline complexes has been successfully studied using the multi-technique methodology based on X-ray absorption fine structure spectroscopy. A distorted square planar geometry around Cu(II) ions composed of two bidently coordinated ligands has been found for all the three complexes. Nitrogen as well as oxygen atoms have been identified as active in the binding process. The final three-dimensional molecular models have been proposed for each of the studied complexes.
