“…A number of manganese(II) complexes have been synthesized in which bis (hydrazone) chelating agents may possess various sets of donor atoms, including the N 3 O 2 set [33][34][35][36][37], involved also in the title ligand. In [38], the ligands, 2,6-diacetylpyridine bis(Girard-T/P hydrazone) dichloride were obtained in the form of anhydrous salts, although they were recrystallized from water-ethanol systems.…”

“…The angle between O2MnO49 is 91.04˚ this value reflects that the two water molecules not in trans-form respect to each other but they are lying in cis-form and then they are perpendicular to each other. The bond length between Mn-O30 and Mn-O22 are 2.026 Å and 2.025 Å are longer than that Mn-N26 and Mn-N24 (1.799 Å and 1.800 Å) [29][30][31], while the bond distance between Mn-O H2O vary from 1.845 Å and 1.846 Å [32,33]. Also, the angles around Mn(II) with surrounding oxygen atoms vary from 73.44˚ to 166.15˚; these values agree with these expected for a distorted octahedron.…”

ABSTRACT. 4,6-Bis(4-chlorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (L) reacted with Mn(II), Fe(III), Co(II) and Ni(II) in methanol and acetone as a solvent at room temperature to form a new solid complexes. The isolated complexes were characterized by elemental analysis, magnetic properties, conductance measurements, mass, IR, UV-Vis and 1 H NMR spectroscopic methods and thermal analyses. The thermogravimetric and infrared spectroscopic data confirmed the presence of water in the composition of the complexes and the ligand reacted as a bidentate. The metal -ligand binding in metal complexes is predicted using density functional theory. The ligand and their metal complexes were also evaluated for their antibacterial activity. The complexes showed high activities compared with free ligand.

Two new Schiff base ligands (L 1 , L 2 ) have been prepared from the reaction of 2,6-diacetylpyridine and 2-pyridinecarboxyaldehyde with 4-amino-2,3-dimethyl-1-phenyl-3-pyrozolin-5-on, and their Co(II), Cu(II), Ni(II), Mn(II), and Cr(III) metal complexes have also been prepared. The complexes are formed by coordination of N and O atoms of the ligands. Their structures were characterized by physico-chemical and spectroscopic methods. The analytical data shows that the metal to ligand ratio in the Schiff base complexes is 1:2. The Schiff base ligands and all complexes were evaluated for their in vitro antibacterial and antifungal activities by the disc diffusion method. In addition, the genotoxic properties of the ligands were studied.
