Summary
The electrochemical oxidation of anodic Co, Ni and Cu in acetone solutions of 4-aminoantipyrine Schiff base of salicyaldehyde (SAAP) and 2-hydroxy-1-naphthaldehyde (NAAP) [=R(OH)] gave the title complexes in high yields. When neutral mono- or bidentate donors were present in the solution, the products were the 1:1 adducts of mixed complexes. The complexes were characterized by elemental analysis, IR, electronic, and ESR spectra as well as magnetic moment measurements. The thermal (DTA) behaviour and electrical properties of some complexes were investigated in the solid state and correlated with the structure of the complexes.
Zusammenfassung
Die elektrochemische Oxidation von Co, Ni und Cu in Lösungen von 4-Aminoantipyrin-Schiff-Basen von Salicylaldehyd (SAAP) und 2-Hydroxy-1-naphthaldehyd (NAAP) ergab die im Titel genannten Komplexe in hohen Ausbeuten. Bei Anwesenheit neutraler mono- oder bidentater Donoren in Lösung entstehen 1:1-Addukte der gemischten Komplexe. Die Komplexe wurden mittels Elementaranalyse, IR, Elektronen- und ESR-Spektren, sowie mittels Messungen der magnetischen Momente charakterisiert. Von einigen Komplexen wurden thermisches Verhalten (DTA) und die elektrischen Eigenschaften untersucht und mit der Struktur der Komplexe korreliert.
