Kupferkomplexe von Bisamiden: Struktur und Stabilität I

Complex formation between Cu²⁺ and several ligands, each containing two amino and two amide groups, has been studied potentiometrically and spectrophotometrically. A digital computer was used to determine the composition of the complex species formed and to calculate their stability constants. N,N′-diglycyl-1, 2-diaminoethane and its homologues form 5-, 6-, 7-, 8- and 9-membered rings between the two amide groups, respectively. No tendency towards formation of binuclear species has been observed.     

Darstellung und Stabilität von Aroxy-fluor-silanen

Preparation and Stability of Aroxy-fluoro-silanes. Different possibilities for preparation of aroxy-fluoro-silanes (esp. substituted phenoxy-fluoro-silanes) are investigated. The reaction was proved as the best method of preparation. The aroxy-fluoro-silanes are disposed to dismutation reactions.     

Zum Zusammenhang zwischen Ligand-Acidität und Metallkomplex-Stabilität: Abnehmende Stabilität bei zunehmender Basizität

The increase of the stability of metal ion complexes with decreasing basicity of the ligands within different series is discussed with the help of the equation of IRVING & ROSSOTTI [4] [12] and explained in terms of the free energy G of the complexes.
