In this paper, the solid state reactions between potassium tetracyanonickelate(II) and oxalic, malonic, fumaric, succinic, adipic acid are studied, followed by modern techniques such as IR, DRS, XRD and MS. It is found that the reactions occur at room temperature. Ni(CN)~2.xH~2O is obtained as a main product and HCN gas is detected. The acidity of these solid organic acids decreases in the order: oxalic>malonic>fumaric>succinic>adipic acid. Proton is believed to play an important role in the reaction process. And the possible mechanism is discussed.
