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.
