Abstract: A multi-metal Prussisa blue compound Co0.25Mn1.25[Fe(CN)6]·5.9H2O has been synthesized.The magnetic property of the compound was measured.The temperature-dependent magnetic susceptibilities indicate that there exists a ferrimagnetic exchange interaction in the compound,and magnet transition at 9.5 K.It has been confirmed that there exists a spin-glass behave in the compound through Zero-field-cooled (ZFC) and field-cooled (FC) magnetization curves,and AC magnetization curves.The observed value of coercive field (Hc) and remanent magnetization(Mr) for the compound are 230 Oe and 0.072 μβ.Room temperature Mossbauer spectrum reveals a doublet with the isomer shift parameter (-0.15(4) mm/s) and quadrupole splitting (QS=0.41(9) mm/s) characteristic for low-spin Fe(Ⅲ) ions incompounds Co0.25Mn1.25[Fe(CN)6]·5.9H2O.Inaddition,there exists a spin-glass behaviour in the compound.
