Abstract

Chromium(III) complexes of the type Cr(A)(A′)2, Cr(A)2(A′) and Cr(A)3 have been prepared (whereA is either piperidyldithiocarbamate or morpholyldithiocarbamate andA′ is glycine or oxine or acetylacetone moiety). The mixed ligand complexes have been charac terized by elemental analyses, magnetic susceptibility measurements and thermal studies. The complexes show magnetic moment in the range of 3.5–4.3 B.M. which corresponds to three unpaired electrons. TG studies have also been carried out, in order to study the mode of decomposition of the complexes and to evaluate various kinetic parameters.

Zusammenfassung

Es wurden Chrom(III)-komplexe des Typs Cr(A)(A′)2, Cr(A)2(A′) und Cr(A)3 (wobei A entweder Piperidyldithiocarbamat oder Morpholyldithiocarbamat und A′ Glycin, Oxin oder Acetylaceton ist) hergestellt. Die Mischligandenkomplexe wurden mit tels Elementaranalyse, Messungen der magnetischen Suszeptibilität und durch thermische Untersuchungen beschrieben. Die Komplexe weisen ein magnetisches Moment im Bereich 3.5–4.3 B.M. auf, was drei ungepaarten Elektronen entspricht. Es wurden auch TG-Unter suchungen durchgeführt, um die Art und Weise der Zersetzung der Komplexe zu untersuchen und verschiedene kinetische Parameter zu bestimmen.
