Abstract

A study was made of the thermal decomposition of octahedral Co(II) complexes of the type CoLn X 2·mH2O, wheren=2 and 3,m=1,2 and 5 andX=Cl, Br, I, NCS, OAc andv 2So4, in both air and nitrogen atmospheres. It was established that the complexes are completely decomposed below 800° and CoO is formed as final product. The most probable decomposition mechanism was proposed. The tris(ligand) complexes were characterized by elemental analysis, and spectral and magnetic measurements, and all the data suggested the presence of a point group symmetry of type Oh.

Zusammenfassung

Sowohl in Luft als auch in Stickstoffatmosphäre wurde die thermische Zersetzung von oktaedrischen Co(II)-Komplexen der allgemeinen Formel CoLnX2· mH2O (n=2 und 3,m=1, 2 und 5,X=Cl, Br, I, NCS, OAc und SO4) untersucht. Es wurde festgestellt, daß sich die Komplexe unterhalb 800°C vollkommen zu CoO als Endprodukt zersetzen. Der wahrscheinlichste Zersetzungsmechanismus wurde unterbreitet. Die tris-Ligandenkomplexe wurden mittels Elementaranalyse sowie Spektral- und magnetischen Untersuchungen charakterisiert, alle Angaben deuten auf eine Punktsymmetriegruppe vom Typ Oh hin.
