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 II 6MnIII 8(μ4-O) 4(μ3-OH)4]24+ core which is comprised of a non-planar rod-like [MnII 2Mn III 6(μ4-O)4(μ3-OH) 2]12+ unit, with both sides bonded in the form of a [MnII 2MnIII(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. ? 2013 Elsevier Ltd.
