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
通过TG和DTA技术研究了双核Pt(II)配合物与乙酸根,丙酸根,戊酸根和异戊酸根的热分解。与乙酸(PtAA)形成的Pt(II)配合物稳定至343.15 K,与丙酸(PtPrA)形成的Pt(II)稳定物,至戊酸(PtVA)形成的Pt(II)复合物稳定高达T = 313.15 K,具有异戊酸(PtIvA)的Pt(II)络合物在408.15 K时稳定。一年后通过热重分析再次研究了PtAA络合物。在Pt(II)配合物与羧酸热分解后,仅在PtVA配合物和PtAA配合物中(一年后研究),最终残留物仅包含铂,而在其余配合物中,固体残留物为铂和碳化铂(PtC2,Pt 2 C 3)。
