Thermolyse von Cyanokomplexen. VII. Über die Thermischen Zersetzungsreaktionen der Hexacyanokobalte(III); Ligandenumlagerungen bei der Thermolyse

Thermolysis of cyano complexes. VII. On the thermal decomposition of hexacyanocobaltate(III); ligand exchange during thermolysis The thermal decomposition of hexacyanocobaltates(III) yields, as products of successive intramolecular redox reactions, first dicyan and Co^II(Co^III)-complexes, then Co^IICo^II]-complexes and simple Co^II(CN)₂, respectively, and finally Co^ICN and elemental Co, respectively. All the compounds of the Co^III(NH₃)₆]³⁺ cation with the cyanometallate anions of Co, Fe, Cr, Mn, Ni, Mo yield the same DTA curve as Co(NH₃)₆]Co(CN)₆] does; in the case of Ni and Cr, which are capable of forming ammine complexes, simultaneous mutual ligand exchange occurs.
