The synthesis and characterization of three ligands and their respective heterobinuclear FeIIIZnII complexes were carried out, with the goal of mimicking the active site of purple acid phosphatases (PAPs). The ligand 2-hydroxy-3-(((2-hydroxy-5-methyl-3-(((2-(pyridin-2-yl)ethyl)(pyridin-2-ylmethyl)amino)methyl)benzyl)(pyridin-2ylmethyl)amino)methyl)-5-methylbenzaldehyde (H2L2) was synthesized and its complex (FeIIIZnIIL2) was used as a basis for comparison with similar complexes previously published in the literature. Subsequent modifications were conducted in the aldehyde group, where 1,2-ethanediamine and 1,4-diaminobutane were used as side chain derivatives. The compounds FeIIIZnIIL2 (1), FeIIIZnIIL2-et (2) and FeIIIZnIIL2-but (3) were characterized by spectroscopic methods (infrared and UV-Vis) and ESI-MS spectrometry. Theoretical calculations were performed to provide insights into the complex structures with FeIIIZnII structures. The hydrolytic activity was analyzed both with the model substrate 2,4-BDNPP and with DNA catalyzed by complexes 1, 2 and 3.

The synthesis of pyridine alcohol based ruthenium carbonyl clusters Ru3(hep)2(CO)8 (1), Ru3(hpp)2(CO)8 (2), and Ru3(bhmp-H)2(CO)8 (3) {hep-H = 2-(2-hydroxyethyl)pyridine, hpp-H = 2-(3-hydroxypropyl)pyridine and bhmp-H2 = 2,6-bis(hydroxymethyl)pyridine} has been carried out by the reaction of the corresponding pyridine-alcohol ligands with Ru3(CO)12. Clusters 1-3 have been characterized using elemental analysis, NMR, FT-IR, mass spectrometry and single-crystal X-ray structures. The clusters were explored for the selective catalytic transformation of primary amines into secondary amines using alcohols as the mono-alkylating agents via hydrogen transfer reactions. All three display efficient catalytic activity with 1 being the most effective.
