Abstract

M(ADNU)2 complexes [whereM=Cu(II), Ni(II), Pd(II) and Pt(II); HADNU=6-amino-1,3-dimethyl-5-nitroso-uracil], Co(ADNU)3·5H2O, Pt(ADNU)2Cl2·0.5H2O, Pd(ADU)2 and Pt(ADU)2Cl2 (where HADU=1,3-dimethyl violuric acid) have been synthesized and characterized by elemental analysis, IR, magnetic measurements and thermal analysis (TG and DSC). All the isolated complexes of formulasM(ADNU)2 orM(ADU)2 show a square planar geometry, whereas the others are octahedral. Both ligands coordinate in bidentate form through the nitrogen and oxygen atoms of the 5-nitroso and 6-oxide groups.

Zusammenfassung

Komplexe des TypesM(ADNU)2 [M=Cu(II), Ni(II), Pd(II), Pt(II); HADNU=6-Amino-1,3-dimethyl-5-nitroso-uracil], Co(ADNU)3·5H2O, Pt(ADNU)2Cl2·0.5H2O, Pd(ADU)2 und Pt(ADU)2Cl2 (mit HADU=1,3-dimethylviolursäure) wurden synthetisiert und mittels Elementaranalysen, IR, magnetischen Messungen und Thermoanalyse (TG und DSC) charakterisiert. Alle isolierten Komplexe der allgemeinen FormelnM(ADNU)2 oderM(ADU)2 waren von quadratisch planarer Geometrie, während die anderen sich als octaedrisch erwiesen. Beide Liganden komplexieren zweizähnig über die Stickstoff- und Sauerstoffatome der 5-Nitroso- und 6-Oxo-Gruppen.
