Abstract

The preparation and crystal structure of a decametallic Mn^II carboxylate cluster containing neutral 2-pyridinealdoxime, (py)C(H)NOH, and its anion, (py)C(H)NO^-, is reported. The reaction between Mn(O₂CPh)₂ · 2H₂O and (py)C(H)NOH in CH₂Cl₂, in the presence of NH₄PF₆, produces the complex [Mn₁₀(O₂CPh)₁₂{(py)C(H)CNO}₆ {(py)C(H)NOH}₂](PF₆)₂ · 2.6CH₂Cl₂ · 1.3H₂O (1 · 2.6CH₂Cl₂ · 1.3H₂O) in good yield. The cationic complex consists of ten Mn^II ions assembled together by four η¹:η¹:η³:μ₄ and two η¹:η¹:η²:μ₃ oximato(-1) ligands, and four η¹:η²:μ₃PhCO₂ ^- ligands to form an unprecedented {Mn^II₁₀ (μ -OR)₄ (μ - OR^′)₂ (μ₃ - OR^′)₄}^{10 +} core, where R = PhCO and R′ = (py)C(H)N. Peripheral ligation is provided by a combination of bridging benzoates and chelating (py)C(H)NOH ligands. Dc magnetic susceptibility studies reveal the presence of dominant antiferromagnetic interactions leading to a spin ground-state of S_T = 0. A survey of the ternary Mn^II / RCO₂^- / (py) C (H) NOH reaction system is attempted with comparisons to previously reported complexes.
