Synthesis, properties and thermal decomposition of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) succinates

Vol. 72, nr 3

498-503

Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) succinates were prepared as solids with general formula MC4H4O4xnH2O, where n=3 for M=Ni, Co,n=2 for M=Cd and n=0 for M=Cu, Zn. IR spectra and X-ray diffractograms were recorded and solubilities in water and thermal decomposition in static air were investigated. During heating the hydrated complexes of Co(II), Ni(II) and Cd(II) lose all water molecules in one step. All complexes of Co(II), Ni(II) and Cd(II) lose all water molecules in one step. All anhydrous complexes decompose to oxides MO with intermediate formation of free metals (Ni, Co, Cu) or oxocarbonates (Zn, Cd).
