Abstract

Formation of nitrogen ligated complexes of types NiL6X2, NiL4X2, NiL2X2 and NiL1X2 (whereL=pyridine, 2-, 3- and 4-methyl-pyridine andX=F, Cl, Br, I) have been studied by traditional preparative methods, i.e. from solutions and by solid-gas phase chemisorption. Quaternary mixed complexes were obtained by chemisorption from heated intermediates. The complexes thus formed were further analysed by simultaneous TG-DTG-DTA. Effects of the ligands on stoichiometry and thermal properties of the complexes are discussed.

Zusammenfassung

Mittels üblicher präparativer Methoden, wie z.B. aus Lösung und mittels Feststoff-Gasphasen-Chemisorption wurde die Bildung von Stickstoffkomplexen des Types NiL6X2, NiL4X2, NiL2X2 und NiL1X2 (mitL=Pyridin, 2-,3- und 4-Methylpyridin und mitX=F,Cl,Br,I) untersucht. Durch Chemisorption erhitzter Intermediäre erhält man quaternäre Mischkomplexe. Die auf diese Weise hergestellten Komplexe wurden ferner mittels simultane TG-DTG-DTA analysiert. Weiterhin wurde der Einfluß der Liganden auf Stöchiometrie und thermische Eigenschaften der Komplexe besprochen.
