Abstract:
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.

Atomic Nuclei: Types of Nuclear Relaxation
In spin–lattice or longitudinal relaxation, the excited spins exchange energy with the surrounding lattice as they return to the lower energy level. Among several mechanisms that contribute to spin–lattice relaxation, magnetic dipolar interactions are significant. Here, the excited nucleus transfers energy to a nearby...
