Abstract: A multi-metal Prussisa blue compound Ni1.15Mn0.35[Fe(CN)6]·6H2O has been synthesized.The temperature-dependentmagnetic susceptibilities of the compound were measured.These results indicate that there exist a ferromagnetic exchange interaction in the complexes.It undergoes a paramagnetic to ferrmagnetic transition at 20 K.According to Curie-Weiss law,paramagnetic Curie temperature (θ) is 13.81 K and the Curie-Weiss constant (C) is 2.21 cm3·K·mol-1.The observed value of coercive field(Hc) and remanent magnetization (Mr) for the compound are 0.172 T and 0.682 uB.This value of Hc is much higher than those most reported Prussian blue analogues.In addition,there exists a spin-glass behaviour in the compound.

Key words: Prussian blue analogue, magnetic transition, ferromagnetic interaction, spin glass
