| Popis: |
Some new compounds of fumaric acid and crotonic acid with cobalt and nickel have been prepared in aqueous solution. These compounds, which have been characterized by analyses, magnetic moments, vibrational and electronic spectra, have polymeric octahedral structures. They are all hydrated, with the exception of the cobalt compound of crotonic acid, which is anhydrous. The thermal behaviour of the compounds has been studied by thermogravimetry and differential thermal analysis. Thermal decomposition studies show that the hydrated compounds lose water followed by organic ligand to give the metal oxide. The anhydrous compound loses organic ligand to give the metal oxide. |
