Abstract: | 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 CoII(CoIII)-complexes, then CoII[CoII]-complexes and simple CoII(CN)2, respectively, and finally CoICN and elemental Co, respectively. All the compounds of the [CoIII(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. |
