Abstract

A new [Mn₁₄(μ₄-O)₄(μ₃-OH) ₄(L)₄(O₂CPh)₁₄(OMe) ₂]·2CH₂Cl₂ (1·2CH ₂Cl₂) cluster, where H₂L = N-salicylidene-o- aminophenol, was synthesized by reacting the [Mn₆O₂(O ₂CPh)₁₀(DMF)₄] precursor with tridentate ligands. The structure of the tetradecanuclear complex features a [Mn ^II₆Mn^III₈(μ₄-O) ₄(μ₃-OH)₄]²⁴⁺ core which is comprised of a non-planar rod-like [Mn^II₂Mn ^III₆(μ₄-O)₄(μ₃-OH) ₂]¹²⁺ unit, with both sides bonded in the form of a [Mn^II₂Mn^III(μ₃-OH)]⁶⁺ triangle. Direct current (dc) magnetic susceptibility measurements of the complex indicate the existence of intramolecular antiferromagnetic interactions between the metal ions, with a ground state of S = 2. The complex exhibits frequency-dependent out-of-phase signals in alternating current (ac) magnetic susceptibility measurements, suggesting slow magnetic relaxations.
