Abstract

The chloro complexes of cobalt, nickel and copper with 3-phenylpyridine were prepared in ethanolic solution from which solid compounds were isolated. The cobalt and copper complexes have stoichiometry M2LCl4 while the nickel complex has stoichiometry NiLCl2. The suggested structure for the cobalt and copper complexes is tetrahedral, while for the nickel complex it is octahedral. Thermal analysis studies show that the cobalt and copper complexes form intermediate complexes before their metal oxides are produced. The nickel complex also forms an intermediate complex and then nickel chloride before the nickel oxide is obtained.

Zusammenfassung

In einer ethylalkoholischen Lösung wurden die Chlorokomplexe von Kobalt, Nickel und Kupfer mit 3-Phenylpyridin hergestellt und dann als Feststoffe isoliert. Die Kobalt- und Kupferkomplexe haben die Stöchiometrie M2LCl4, der Nickelkomplex dagegen die Stöchiometrie NiLCl2. Dies deutet auf eine tetraedrische Struktur der Kobalt- und Kupferkomplexe sowie auf eine oktaedrische Struktur des Nickelkomplexes hin. Thermoanalytische Untersuchungen zeigen, daß die Kupfer- und Kobaltkomplexe intermediäre Komplexe bilden, bevor ihre Metalloxide entstehen. Der Nickelkomplex bildet vor der Bildung des Metalloxides erst einen intermediären Komplex und anschließend Nickelchlorid.
