    Description / Table of Contents: Polyol Metal Complexes. X. Lead(II) meso-Oxolane-3,4-diolate(2-) Monohydrate - a Polymeric Lead Alkoxide from Aqueous SolutionIn the colourless crystals of Pb(C4H6O3) · H2O (P21/c, a = 569.8(3), b = 607.6(4), c = 1856.9(9) pm, β = 89.90(4)°, V = 642.9(6) · 106 pm3, Z = 4), lead(II)- and meso-oxolane-3,4-diolate(2-) ions form a one-dimensional coordination polymer; PbII is coordinated with four bridging alkoxide O-atoms (mean distance: 234.5 pm); some 100 pm more distant two μ-O-atoms of water molecules coordinate the lead ion.

    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.
