Abstract: | The thermal decomposition of the binuclear Pt(II) complexes with acetate, propionate, valerate and izovalerate ligands were
studied by TG and DTA techniques. The Pt(II) complex with acetic acid (PtAA) was stable up to 343.15 K, Pt(II) complex with
propionic acid (PtPrA) was stable up to 323.15 K, Pt(II) complex with valeric acid (PtVA) was stable up to T=313.15 K and Pt(II) complex with isovaleric acid (PtIvA) was stable up to 408.15 K. The PtAA complex was investigated again
after a year by thermogravimetric analysis. After the thermal decomposition of the Pt(II) complexes with carboxylic acids,
only in the PtVA complex and PtAA complex (investigated after a year) the final residue contains only platinum, while in the
rest complexes the solid residue was a mixture of platinum and platinum carbides (PtC2, Pt2C3). |
