| Özet |
| Two new mononuclear Cu (II) complexes,[Cu (H3pzpz)(NO3)]∙ NO3∙ H2O (1) and [Cu (H3tpz) Cl] 2∙ 2 (Cl)∙ 5H2O (2), with pyrazine-modulated oligo-α-pyridylamine ligands N2-(pyrazin-2-yl)-N6-(6-(pyrazin-2-ylaminopyridin-2-yl) pyridin-2, 6-diamine (H3pzpz) and N2-(pyrazin-2-yl)-N6-(6-(pyridin-2-ylaminopyridin-2-yl) pyridin-2, 6-diamine (H3tpz), have been synthesized, structurally characterized, and their antimicrobial efficacy has been studied. Single-crystal X-ray diffraction revealed that the central Cu (II) atom in complexes 1 and 2 was located in a distorted trigonal bipyramidal geometry. In both complexes, H3pzpz or H3tpz acts as a tetradentate ligand; it coordinates the copper (II) ion in an all-anti conformation, and the Cu (II) atom is five-coordinated in a distorted trigonal bipyramidal geometry. The distorted trigonal bipyramidal structures of the compounds are consistent with both the «inverted type» EPR spectra, in which g‖ is smaller than g┴, and two spin-allowed transitions in the visible region of their electronic spectra. The complexes are built into a three-dimensional network by extensive hydrogen bonding and intermolecular π-π interactions, which stabilize the crystal packing. The antimicrobial efficacy of 1 and 2 was evaluated against P. aeruginosa, M. phlei, A. niger, and P. chrysogenum. Both complexes demonstrated significant potency, with complex 2 showing superior activity, particularly against P. aeruginosa with an inhibition zone of 26 mm compared to 20 mm for complex 1 (at 100 µg/mL). The sulfur-binding affinity and redox activity of these metal complexes also present potential for neutralizing hydrogen sulfide (H₂S) in … |
