| Abstract: | Pseudohalide complexes of copper(II) with aliphatic bidentate amines, [Cu(N3)2(N,N-diEten)]2 1, [Cu(NCO)2(N,N-diEten)]2 2, [Cu(NCO)2(N,N-diMeen)]2 3, [Cu(N3)(NCS)(N,N'-diMeen)]2 4 and [Cu(N3)(NCO)(N,N-diMeen)]2 5 (N,N-diEten=N,N-diethylethylenediamine; N,N-diMeen=N,N- dimethyl-ethylenediamine and N,N'-diMeen = N,N'-dimethylethylenediamine), were prepared, characterized and their thermal behavior was investigated by TG curves. According to thermal analysis and X-ray diffraction patterns all compounds decomposed giving copper(II) oxide as final product. The mechanisms of decomposition were proposed and an order of thermal stability was established.This revised version was published online in November 2005 with corrections to the Cover Date. |
