文摘
A new complex (1) of Prussian blue analogue with the composition of K0.2Mn1.4Cr(CN)6·6H2O was preparedand characterized structurally as well as magnetically. The crystal structure of complex 1 was determined byX-ray diffraction analysis. The results indicate that complex 1 consists of a 3D cubic lattice similar to those ofMn3[Cr(CN)6]2·xH2O, Mn3[Co(CN)6]2·xH2O, Cd3[Cr(CN)6]2·xH2O, and Cd3[Co(CN)6]2·xH2O. Magnetic measurementsshow that complex 1 is a ferrimagnet with Tc = 66 K. It is interesting to note that the magnetic behavior of complex1 can be substantially modulated through a dehydration/rehydration treatment. The Tc value of this ferrimagnetincreases to 99 K after dehydration reaching a 23.4% weight loss, and it decreases back to 66 K after the dehydratedsample reabsorbs water molecules.
