    Description / Table of Contents: Polyol Metal Complexes. XIII. Na2[Be(C4H6O3)2] · 5H2O and Na2[Pb(C4H6O3)2] · 3H2O - Two Homoleptic Bis Polyolato Metallates with Beryllium and with LeadNa2[Be(C4H6O3)2] · 5H2O (1) and Na2[Pb(C4H6O3)2] · 3H2O (2) crystallize from concentrated, alkaline aqueous solutions. The polyol anhydroerythritol is deprotonated twice in the mononuclear, homoleptic complex anions. The preference of beryllium for the binding of cis-furanoid diols is shown. In 2, a stereochemically active lone pair at the central atom is the reason for the construction of low dimensional aggregates from three plumbate and three sodium ions.
    Notes: Na2[Be(C4H6O3)2] · 5H2O (1) und Na2[Pb(C4H6O3)2] · 3H2O (2) kristallisieren aus konzentrierten wäßrig-alkalischen Lösungen. In den einkernigen, homoleptischen Komplexanionen liegt das Polyol Anhydroerythrit als doppelt deprotonierter Chelatligand vor. Die Präferenz des Berylliums für cis-furanoide Diole wird gezeigt. In 2 führt ein stereochemisch aktives Elektronenpaar am Zentralmetall zum Aufbau eines niederdimensionalen Aggregats aus drei Plumbat- und drei Natrium-Ionen.

    Notes: Polyol Metal Complexes. 27. Bis-Diolato Antimonates(III) with Guanosine as the DiolThe complex anions of K3[SbIII(Guo1,2′,3′H-3)2] · 10 H2O (1) and [Co(NH3)6][SbIII(Guo1,2′,3′H-3)2] · 9 H2O (2) are four-coordinate homoleptic bis(diolato)antimonate(III) species. The guanosine trianions act as carbohydrate ligands through their cis-furanoidic ribosyl moiety, thus forming no nucleobase-metal bonds.
