Abstract:
Three new complexes containing MnMoIII zigzag chains have been synthesized and structurally characterized. The crystal structure of complex 3 consists of two linkage isomers of the MoIIIMn chains, which correspond to 1 and 2, respectively. Both complex 1 and 3 show slow magnetic relaxation behavior with an energy barrier of Δ/kB = 69.5 K and 68.8 K, respectively, whereas complex 2 is a simple paramagnet. The linear apical MoIII-CN-MnII pairs provide the required magnetic anisotropy for the slow magnetic 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...
