    Description / Table of Contents: Polyol Metal Complexes. 18. Multinuclear Cuprates(II) with deprotonated Glycerol as a ligandNa3[Cu3(GlycH-3)3] · 7H2O(1) and Na3[Cu3(GlycH-3)3] · 1/3NaNO3 · 10H2O (4) (Glyc = glycerol) crystallize from aqueous solutions containing sodium hydroxide. The trinuclear tricuprate(II) ions exhibit Cs-symmetry (approximately for 1). The central Cu3O3 cyclus has an envelope conformation one, of the copper atoms being out of plane. Ba2(ox)[Cu2(μ-OH)2(Glycl, 2H2)2] · 10H2O (2) (ox = oxalate) is formed by oxidation with air from respective solutions containing barium hydroxide.
    Notes: Na3[Cu3(GlycH-3)3] · 7 H2O (1) and Na3[Cu3(GlycH-3)] · 1/3 NaNO3 · 10 H2O (4) (Glyc = Glycerin) kristallisieren aus wäßrig-alkalischer Lösung. Die dreikernigen Tricuprat(II)-Ionen sind (bei 1 angenähert) Cs-symmetrisch, der zentrale Cu3O3-Ring liegt in einer Briefumschlagkonformation mit einem Kupferatom als weggeklappter Ecke vor. Ba2(ox)[Cu2(μ-OH)2(Glycl, 2 H-2)2] · 10 H2O (2) (ox = Oxalat) entsteht durch Luftoxidation aus entsprechenden Lösungen mit Bariumhydroxid.
