摘要：

The coordinations compounds (NH4)[Fe(C4H4O5)(OH)(2)].0.5H(2)O, [Ni(C4H4O5)].3H(2)O and [Zn(C4H4O5)].5H(2)O were synthesized by a precipitation method and characterized by chemical analysis, spectral (IR, UV-VIS) and magnetical investigations. In the range 50-600degreesC stepped thermal decompositions occur with formation of anhydrous malates, malonates, oxoacetates (iron and nickel compounds) and hydroxocarbonate (Zn compound) as intermediates observed by FT-IR spectroscopy. alpha-Fe2O3, NiO and ZnO constitute the final decomposition products.
