THERMAL-DECOMPOSITION OF SOME N-OXIDE COMPLEXES OF COBALT(II), NICKEL(II) AND COPPER(II) CARBOXYLATES

Thermal decomposition of mono pyridine N-oxide complexe; of cobalt(II), nickel(II) and copper(II) propionates and mono quinoline N-oxide complex of copper(II) ben zoate has been studied by TG and DTA techniques. These dimeric complexes are stable upto 350-380 K and decompose in two stages: (i) successive elimination of the two ligand molecules (mostly endothermic); and (ii) decomposition of the resulting anhydrous metal(II) carboxylates by an exothermic multistep process in air. © 1979 Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest.
