Slow magnetic relaxation in an octanuclear manganese chain.
A one-dimensional chain containing a mixed-valence octanuclear manganese(II,III) building unit, (NEt(4))(2n)[Mn(8)O(2)(salox)(6)(N(3))(8)(MeOH)(3)](n) (H(2)salox = salicylaldoxime), was synthesized and characterized structurally and magnetically. Each building unit contains a [Mn(II)(2)Mn(III)(6)O(2)](18+) structural topology. The frequency dependence of the out-of-phase component in alternating current magnetic susceptibilities and hysteresis loops for the complex indicates single-chain-magnet-like behavior.
