Abstract

The crystal structures and thermal behaviour of [Cu(py)2(NCS)2] (at 293) and [Cu(4-Mepy)2(NCS)2] and 180 K) complexes have been compared with their different temperature behaviour. It was found that the thermal stability of coordinated thiocyanate ligands in the course of thermal decomposition depends not only on the properties of the ligand L, but it is related to the arrangement of the thiocyanatocopper chains in the crystal structures.

Zusammenfassung

Es wird die Kristallstruktur und das thermische Verhalten der Komplexe [Cu(Py)2(NCS)2] (bei 293 K) und [Cu(4-MePy)2(NCS)2] (bei 293 und 180 K) untersucht. Man fand, daß die thermische Stabilität der koordinierten Thiocyanatliganden im Verlaufe der thermischen Zersetzung nicht nur von den Eigenschaften des Liganden L abhängt, sondern auch in Beziehung zu Form und Anordnung der Thiocyanatokupferketten innerhalb der Kristallstruktur steht.
