Salicylate‐Mediated Assembly of the Diserete Mixed‐Valence Nonanuclear Manganese Complex [Mn₉O₄(O₂CPh)₈(sal)₄(salH)₂(py)₄] (salH₂ = salicylic acid, py = pyridine)

Abstract

The complex 1 can be regarded as a kind of “inorganic sandwich compound” without metal–metal bonds: It contains an MnII atom sandwiched between two relatively flat [MnO2] moieties. 1 is obtained in the form of black crystals on treatment of [Mn3O(O2CPh)6(py)2(H2O)] in acetonitrile with solid salicylic acid. Noteworthy is the high yield of ca. 40%. The magnetic susceptibility of 1 points to strong coupling of the lone electrons.
