文摘
A 5d鈥?d bimetallic compound was prepared by self-assembling [W(CN)8]3鈥?/sup> 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.
