Issue Date: | 1-Jan-1997 | Journal: | Journal of Thermal Analysis | Abstract: | Solvate complexes of UO22+ and N(1), N(4)-bis(salicylidene)-S-methylisothiosemicarbazone, (H2Me-L1), of general formula [UO2(Me-L1)S] (S= H2O, MeOH, EtOH, Py, DMF and DMSO) were synthesized. The methanolic UO22+ adducts of N(1)-benzoylisopropylidene-N(4)-salicylidene-S-alkylisothiosemicarbazone, (H2R-L2, R=Me, Prn) of general formula [UO2(R-L2)-MeOH], were also prepared. Thermal decomposition of the complexes was investigated in air and argon. The complexes decompose to α-U3O8 in air, while in argon the decomposition is not completed up to 1000 K. The temperature and the mechanism of decomposition of the complexes are a function of the solvent belonging to the inner coordination sphere. © 1997 Akadémiai Kiadó. | URI: | https://open.uns.ac.rs/handle/123456789/11682 | ISSN: | 03684466 |
