    Description / Table of Contents: Ternäre Komplexe einiger Seltener Erd-Ionen mit 1,2-Diaminohexantetraessigsäure und Hydroxysäuren1:1:1-Systeme aus Seltenen Erd-Ionen, CDTA und Hydroxysäuren wurden pH-metrisch untersucht. Die Bildungskonstanten (log KMLL′) und freien Bildungsenergien (ΔF°) der Komplexe wurden berechnet. Die Stabilitätsreihe in bezug auf die Metallionen ist: La 〈 Nd 〈 Gd 〈 Dyrin bezug auf die Hydroxysäuren: Weinsäure 〈 Apfelsäure.
    Notes: 1:1:1, Rare earth ions-CDTA-hydroxy acids ternary systems have been studied pH-metrically. The formation constants (log KMLL′) and free energies of formation (ΔF°) of the resulting octa-coordinated metal ion mixed-ligand complexes have been calculated. The order of stability in terms of metal ions has been reported as: La 〈 Pr 〈 Nd 〈 Gd 〈 Dy and in terms of hydroxy acids as: TAR 〈 MAL.

    Description / Table of Contents: Polychalcogenoanions of the Transition Metals. IV. Novel Redox Condensation Reactions of MoO2S22- in H2O and Preparation of Di-μ-sulfido Complexes of MovMoVIO2S22- polymerizes after protonation in aqueous solution under physiological conditions forming polynuclear complexes with η-S22- ligands (for example [Mo2vO2S2(S2)2]2-). From the solution other di-μ-sulfido Mov complexes as for example [Mo2O2S2(Et2dtc)2] can be easily obtained.
    Notes: MoVIO2S22- kondensiert nach Protonierung im wäßrigen Medium unter physiologischen Bedingungen (bei pH-Werten von etwa 7) zu mehrkernigen schwefelverbrückten Komplexen mit η-S22--Liganden (wie z. B. [Mo2VO2S2(S2)2]2-) bei einem ebenfalls ablaufenden intramolekularem Redoxprozeß. Aus der Lösung lassen sich auch andere Di-μ-sulfido-MoV-Komplexe wie z. B. [Mo2O2S2(Et2dtc)2] isolieren.
