Manganese(III) complexes [MnL 2 1 ]BPh4 (1) and [MnL 2 2 (MeOH)2]BPh4 (2) were synthesized (HL1 = 2-{N-[2-(2-pyridyl)ethyl]iminomethyl}-6-methoxyphenol and HL2 = 2-{N-[2-(2-pyridyl)ethyl]iminomethyl}-4-methylphenol) and characterized. The crystal structures were determined by single crystal X-ray crystallography for 1 and 2 and magnetic properties were characterized by magnetic susceptibility. Compounds 1 and 2 crystallized in the triclinic system with space groups P-1. The crystal structure of 1 showed that the central manganese(III) ions were coordinated by four nitrogen and two oxygen atoms of two ligands in trans positions, exhibiting a pseudo-octahedral geometry. On the other hand, the crystal structure of 2 showed that the manganese(III) ions were coordinated by the two nitrogen and two oxygen atoms of two ligands and two methanol solvent molecules. The variable temperature-dependence magnetic susceptibilities have shown that the compounds 1 and 2 manganese(III) oxidation state; there is no magnetic interaction between complexes.

Sixteen new 3d-4f binuclear complexes have been obtained using two Schiff-base ligands, Hvalampy and Hvalaepy, derived from the reaction of o-vanillin and 2-aminomethyl-pyridine or 2-(2-aminoethyl)-pyridine, respectively. Hvalaepy ligand: [Zn(valaepy)sub

Twelve iron(III) complexes [FeIII(LX)2]ClO4, where (LX)- is the deprotonated form of a series of asymmetric ligands containing pyridine and substituted phenol moieties (XPh(OH)-CH=N-(CH2)n-Py that X = H, 5-Br, 5-NO2, 5-OMe, 4-OMe, 3-OMe, and n = 1, 2), were synthesized and characterized by H NMR, IR, UV-Vis spectroscopy, mass spectrometry, and elemental analysis. Formation constants were measured using UV-Vis spectrophotometric titration at constant ionic strength (0.10 M NaClO4) at 25 (±0.1)°C. The trend of the complex formation of Fe(III) ion with a given tridentate ligand decreases as follows: 5-OMe > 5-H > 5-NO2 > 5-Br 5-OMe > 4-OMe > 5-OMe.
