Abstract

The stability constantsK1=3.6 andK2=1 of Nd(MeOH) x NO 3 2+ and Nd(MeOH) x (NO3) 2 + complexes were determined spectrophotometrically. On the basis of an analysis of the stepwise stability constants ratio it was found that these are inner sphere complexes.

Zusammenfassung

Es wurden die StabilitätskonstantenK1=3.6 undK2=1 der Komplexe Nd(MeOH) x NO 3 2+ und Nd(MeOH) x (NO3) 2 + spektrophotometrisch bestimmt. Basierend auf einer Analyse der stufenweisen Stabilitätskonstanten wurde festgestellt, daß es sich um Komplexe der inneren Sphäre handelt.
