Abstract

A new complex (1) of Prussian blue analogue with the composition of K _0.2Mn_1.4Cr(CN)₆·6H₂O was prepared and characterized structurally as well as magnetically. The crystal structure of complex 1 was determined by X-ray diffraction analysis. The results indicate that complex 1 consists of a 3D cubic lattice similar to those of Mn₃[Cr(CN)₆]₂·χH₂O, Mn₃[Co(CN)₆]₂·χH₂O, Cd₃[Cr(CN)₆]₂·χH₂O, and Cd₃[Co(CN)₆]₂·chi;H₂O. Magnetic measurements show that complex 1 is a ferrimagnet with T_c = 66 K. It is interesting to note that the magnetic behavior of complex 1 can be substantially modulated through a dehydration/rehydration treatment. The T _c value of this ferrimagnet increases to 99 K after dehydration reaching a 23.4% weight loss, and it decreases back to 66 K after the dehydrated sample reabsorbs water molecules.
