The thermal decomposition processes and hydrogenation reactions of K₂Co[Fe(CN)₆]·H₂O and Co₃[Fe(CN)₆]·7H₂O in hydrogen were studied by GC to discern the gas products and by Mossbauer spectroscopy, IR and XRD to determine the structure of the solid products. Their decomposition processes may be divided into three steps: (1) dehydration, (2) reduction of Fe (Ⅲ) to Fe(Ⅱ), and (3) rupture ofthe triple bond of C≡N^- by hydrogenation to evolev NH₃ and CH₄. Iron-Cobalt alloy was formed at the final step of decomposition. K₂Co[Fe(CN)₆)·H₂O and Co₃[Fe(CN)₆]·7H₂O may be considered as a multibond activation model of bimetal coordination, since CN^- acts as a typical ambident ligand in it. The activation of CN^- triple bond has been discussed in terms of hydrogenation reaction.
