    Description / Table of Contents: Heteronuclear Coordination Compounds with Metal - Metal Bonds. VIII. New Heterodinuclear Complexes with Bonds between Copper(I) and Manganese(-I), Iron(-I), or Cobalt(-I)[(en)Cu—Mn(CO)5] (1a), [(dien)Cu—Mn(CO)5] (1b), [(en)Cu—Fe(CO)3(NO)] (2a), [(dien)Cu—Fe(CO)3(NO)] (2b), [(en)Cu—Co(CO)4] (3a), and [(dien)Cu—Co(CO)4] (3b) are new heterobinuclear metal - metal bonded complexes. The geometry of the [Mn(CO)5]-, [Fe(CO)3(NO)]-, and [Co(CO)4]- ions is distorted only to a less extend in accord with a heteropolar bond to copper.
    Notes: [(en)Cu—Mn(CO)5] (1a), [(dien)Cu—Mn(CO)5] (1b), [(en)Cu—Fe(CO)3(NO)] (2a), [(dien)Cu—Fe(CO)3(NO)] (2b), [(en)Cu—Co(CO)4] (3a) und [(dien)Cu—Co(CO)4] (3b) sind neue heteronukleare Zweikernkomplexe mit Metall - Metall-Bindungen, in denen die Geometrie der [Mn(CO)5]--, [Fe(CO)3(NO)]-- und [Co(CO)4]--Ionen durch die Bindung an Kupfer im Sinne einer heteropolaren Wechselwirkung nur wenig verzerrt wird.

    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.

    Description / Table of Contents: Heteronuclear Coordination Compounds with Metal - Metal Bonds. IX. Amine Copper(I) Carbonyl Metalates with Cobalt, Iron, or ManganeseColourless crystals of the carbonyl copper complex [(NH3)3(CO)Cu][Co(CO)4] (1 a) are formed in the reaction of [Cu(NH3)4]Cl and Na[Co(CO)4] (T 〈 - 8°C, pCO = 1 bar); above -5°C and under N2-atmosphere 1 a converts to [(NH3)2CuCo(CO)4] (C), which serves as a starting material for the synthesis of new copper cobaltates: the amines N-amino piperidine, N,N-dimethyl ethylenediamine (dmed) and N-benzyl N,N′-dimethyl ethylenediamine (bn-dmed) replace NH3 to form [(C5H10N—NH2)3CuCo(CO)4] (1 b), [(dmed)CuCo(CO)4] (1 c), [(bn-dmed)CuCo(CO)4] (1 d) the Cu—Co-bond remaining intact. [(NH3)2CuFe(CO)3NO] (2 a) is isosteric with C; it is synthesized from [Cu(NH3)4]Cl and Na[Fe(CO)3NO] in aqueous solution; 2 a reacts with N,N,N′,N′-tetramethyl ethylenediamine (tmed) to form [(tmed)(NH3)CuFe(CO)3NO] (2b). The [Mn(CO)5]- ion reacts with ammine copper ions to form the tetranuclear cluster [{(NH3)CuMn(CO)5}2] (3). All new compounds have been investigated by X-ray structure analysis.
    Notes: Farblose Ionenkristalle des Carbonyl-kupfer-Komplexes [(NH3)3(CO)Cu][Co(CO)4] (1 a) entstehen bei der Reaktion von [Cu(NH3)4]Cl und Na[Co(CO)4] (T 〈 - 8°C, 1 bar CO-Druck); oberhalb -5°C und unter N2-Atmosphäre entsteht aus 1 a [(NH3)2CuCo(CO)4] (C), von dem ausgehend weitere Cobaltate zugänglich sind: Die Amine N-Amino-piperidin, N,N-Dimethyl-ethylendiamin (dmed) und N-Benzyl-N′,N′-dimethyl-ethylendiamin (bn-dmed) verdrängen NH3 unter Erhalt der Cu—Co-Bindung zu [(C5H10N—NH2)3CuCo(CO)4] (1 b), [(dmed)CuCo(CO)4] (1 c), [(bn-dmed)CuCo(CO)4] (1 d). Das zu C isostere [(NH3)2CuFe(CO)3NO] (2 a) entsteht bei der Reaktion von [Cu(NH3)4]Cl und Na[Fe(CO)3NO] in wäßriger Lösung; mit N,N,N′,N′-Tetramethylethylendiamin (tmed) wird aus 2 a [(tmed)(NH3)CuFe(CO)3NO] (2 b) erhalten. Mit dem [Mn(CO)5]--Ion bildet sich dagegen unter den für 2 a angegebenen Reaktionsbedingungen der ammoniakärmere, heteronukleare Vierkerncluster [{(NH3)CuMn(CO)5}2] (3). Alle neuen Verbindungen sind durch Einkristallstrukturanalyse gesichert.

    Description / Table of Contents: Polyol Metal Complexes. 17. Crystalline Iron(III) Complexes with Twofold Deprotonated Anhydroerythritol LigandsThree new crystalline ferrates(III) with diolato ligands derived from anhydroerythritol by deprotonation have been synthesized from wet alcoholic and from aqueous solution. Almost colourless, monoclinic crystals of Na2[Fe(AnEryt-H-2)2(OH)] · 0.5 NaNO3 · 3.5 H2O (1) have been prepared from ethanolic solutions. They content mononuclear bis diolato hydroxo ferrate(III) dianions. Trinuclear hexakis diolato μ3-methoxo triferrat(III) tetraanions constitute the anionic part of Na4[Fe3(AnErytH-2)6(OMe)] · 2.5 NaNO3 (2), yellow-green hexagonal crystals of which are formed from wet methanolic solutions. Yellow-green triclinic crystals of Ba2[Fe2(AnEryt-H-2)4(μ-OH)2] · 12 H2O (3) have been precipitated from aqueous solutions. In 3, the anions of 1 are dimerized to give tetrakis diolato di-μ-hydroxo diferrat(III) tetraanions.
    Notes: Drei neue kristalline Ferrate(III) mit doppelt deprotoniertem Anhydroerythrit als Diolato-Liganden wurden aus wasserhaltigem Medium hergestellt. Nahezu farblose, monokline Kristalle von Na2[Fe(AnErytH-2)2(OH)] · 0,5 NaNO3 · 3,5 H2O (1) werden aus wasserhaltigem Ethanol erhalten. Sie enthalten einkernige Bis-diolato-hydroxo-ferrat(III)-Dianionen. Dreikernige Hexakis-diolato-μ3-methoxo-triferrat(III)-Tetraanionen sind in Na4[Fe3(AnErytH-2)6(OMe)] · 2,5 NaNO3 (2) enthalten, das aus wasserhaltigem Methanol in Form hexagonaler, grüngelber Platten kristallisiert. Aus wäßrigen Diolatoferrat-Lösungen bilden sich grüngelbe, trikline Kristalle von Ba2[Fe2(AnErytH-2)4(μ-OH)2] · 12 H2O (3), in dem die Anionen von 1 in dimerer Form vorliegen, nämlich als zweikernige Tetrakis-diolato-di-μ-hydroxo-diferrat(III)-Tetraanionen.
