Cyanide-Bridged W^VMn^III Single-Chain Magnet with Isolated Mn^III Moieties Exhibiting Two Types of Relaxation Dynamics

A 5d–3d bimetallic compound was prepared by self-assembling [W­(CN)8]3– and the MnIII Schiff bases. This neutral complex consists of cyanide-linked WVMnIII anionic chains and isolated MnIII Schiff base cations. We demonstrate that two types of relaxation processes are involved in the system; the low-T dynamics may come from magnetic domain dynamics and the high-T relaxation stems from the anionic chain, revealing single-chain magnet character.
