ABSTRACT / САЖЕТАК:

Pyridoxal-aminoguanidine (PLAG) is a tridentate ligand known for its complexation with different transition metals. These complexes possess promising anticancer, antioxidant, and catalytic activities. In this contribution, two novel Cu(II)-PLAG complexes with different counterions (NO3− and SO42−) were synthesized, and their crystal structures were solved. The structural differences resulted from the size and charge of counterions leading to the square-pyramidal geometry of the first and square-planar geometry of the second. The Hirshfeld surface analysis was employed to obtain quantitative parameters for the stabilization interactions between various atoms. The overall geometry significantly influenced the relative percentages of these interactions.
