An asymmetric dinuclear Mn(III) complex, [Mn2(L1-H)2(OBz)Cl(H2O)]·CH3CN [H2L1-H = N-(2-oxymethylphenyl)salicylideneimine], was synthesized and characterized by single-crystal X-ray analysis. The compound crystallizes in the triclinic space group P1 with a = 10.9807(15), b = 12.3290(17), c = 14.492(2)Å, α = 80.004(10), β = 74.181(8), γ = 64.614(7)°, V = 1701.8(4)Å3, Dcalcd = 1.514 g/cm3, Z = 2. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0376 and 0.0999, respectively, for all 5382 independent reflections. The complex has a bis-μ-alkoxo bridged dinuclear structure with a syn-syn bridged benzoate as an axial ligand. Magnetic measurements of 1 indicate that a weak antiferromagnetic interaction is operative in the dimanganese core with J value of –12.6 cm−1.
