Dinuclear manganese(II,II) and (II,III) complexes, [Mn<SUB>2</SUB>(L-py)(RCOO)<SUB>2</SUB>]ClO<SUB>4</SUB>·<I>n</I>H<SUB>2</SUB>O and [Mn<SUB>2</SUB>(L-py)(RCOO)<SUB>2</SUB>](ClO<SUB>4</SUB>)<SUB>2</SUB>·<I>n</I>H<SUB>2</SUB>O, were prepared, where L-py is 2,6-bis[bis(2-pyridylmethyl)aminomethyl]-4-methylphenolate(1–) and RCOO denotes CH<SUB>3</SUB>COO or C<SUB>6</SUB>H<SUB>5</SUB>COO. X-Ray structure analysis of the mixed valence complex [Mn<SUB>2</SUB>(L-py)(C<SUB>6</SUB>H<SUB>5</SUB>COO)<SUB>2</SUB>](ClO<SUB>4</SUB>)<SUB>2</SUB>·H<SUB>2</SUB>O revealed that the complex cation involves octahedral manganese(II) and manganese(III) centers with N<SUB>3</SUB>O<SUB>3</SUB> donor sets and that the two metal ions are linked by phenolato and two benzoato groups. Magnetic susceptibility measurements over temperature range 80–300 K indicated that both manganese(II,II) and (II,III) complexes exhibit weak antiferromagnetic interaction with spinexchange coupling constant, <I>J</I>=−5–−7 cm<SUP>−1</SUP>. Cyclic voltammograms of the mixed valence complexes showed two quasi-reversible redox couples at ca. 0.5 and ca. 1.0 V (vs. SCE), assignable to the redox reactions of Mn<SUP>II</SUP>–Mn<SUP>III</SUP>/Mn<SUP>II</SUP>–Mn<SUP>II</SUP> and Mn<SUP>III</SUP>–Mn<SUP>III</SUP>/Mn<SUP>II</SUP>–Mn<SUP>III</SUP>, respectively. The comproportionation constants for the reaction (Mn<SUP>III</SUP>–Mn<SUP>III</SUP>)+(Mn<SUP>II</SUP>–Mn<SUP>II</SUP>)\rightleftarrows2(Mn<SUP>II</SUP>–Mn<SUP>III</SUP> at 20°C were estimated as 2–3×10<SUP>9</SUP>.
