The thermal behaviour of mon-oxalato-bis-bipyridine-cobalt(III) complexes

The thermal redox decomposition reactions were determined for [Co(bipy) 2ox]X. nH 2O type coordination compounds (bipy = 2,2′-bipyridine; ox = C 2O 2− 4; X = F −, Cl −, Br −, I −, BIO − 4, BF − 4, HCOO −, H 3CCOO −; n = 0−3). Data were obtained using thermogravimetry and DTA. In the solid phase the thermal reaction pathways were found to be essentially influenced by different anions, X, in the second coordination sphere. The reaction pathways are described and some interpretations of potential reaction mechanisms are proposed.
