Abstract

Systematic syntheses of manganese derivatives with 2-pyridineethanol, 2-pyridinemethanol and 2,6-pyridinedimethanol as chelating ligands have been undertaken to produce [trans-Mn(C5H4N-2-CH2CH2OH)2Cl2] (1), [cis-Mn2(μ-Cl)2(Cl)2(C5H4N-2-CH2CH2OH)2(OH2)2] (2), [cis-Mn2(μ-Cl)2(C5H4N-2-CH2OH)4]Cl2 (3) and [MnCl{η3-C5H3N-2,6-(CH2OH)2}{η2-(C5H3N-2,6-(CH2OH)2)}]Cl (4). The complexes were characterized by single-crystal X-ray diffraction. The oxidation state of the manganese ions in these complexes is 2+. Magnetic data are measured down to 2 K; in dimer complexes (2 and 3) a significant antiferromagnetic interaction is observed between two manganese ions.
