α-Benzoin Oxime in Higher Oxidation State 3d Metal Cluster Chemistry: Structural and Magnetic Study of a New Mn^III₉ Complex

The initial employment of α-benzoin oxime (bzoxH₂) in higher oxidation state 3d metal cluster chemistry has provided access to a new enneanuclear Mn^III complex with an unprecedented metal-core topology consisting of two triangular [Mn₃(μ₃-Ο^2-)(μ-ΟΝ)₃]⁴⁺ fragments connected by a linear [Mn₃(μ-ΟΝ)₆]³⁺ unit. The Mn^III₉ cluster is antiferromagnetically coupled and has an S = 3 spin ground state.
