    Description / Table of Contents: The Crystal Structure of Me3SiI · β-Picoline and Me3SiI · γ-Picoline A Comparison between the Lewis-Bases Pyridine, β-Picoline, and γ-PicolineThe reaction of Iodinetrimethylsilane with β- und γ-Picoline (Pic) leads to solid 1 : 1 compounds Me3SiI · β-Picoline 1, Me3SiI · γ-Picoline 2. The reaction was performed at room temperature. Yellow single crystals were obtained by sublimation. Single crystal X-ray investigations confirm that both compounds are ionic [Me3SiPic]+I-. The comparison of β-Picoline with γ-Picoline and Pyridine (Py) demonstrates that the presence of a methyl group and also its position has no significant influence on the Si—N bond length in compound 1, 2 and on the adduct Me3SiI · Py.
    Notes: Iodtrimethylsilan reagiert mit β- und γ-Picolin (Pic) bei Raumtemperatur zu festen 1 : 1 Addukten (M3SiI · β-Picolin 1, Me3SiI · γ-Picolin 2), die durch Sublimation leicht gelblich gefärbte Einkristalle bilden. Die Röntgenstrukturanalyse beider Verbindungen beweist eine ionische Struktur des Typs [Me3SiPic]+ I-. Der Vergleich von β-Picolin mit γ-Picolin und Pyridin (Py) zeigt, daß die Anwesenheit einer Methylgruppe und auch deren Position keinen signifikanten Einfluß auf die Si—N-Bindungslänge in Verbindung 1, 2 und dem Addukt Me3SiI · Py hat.

    Description / Table of Contents: The Crystal Structure of Tris(N,N-diethyl-N′-benzoylselenoureato)cobalt(III)Co(C12H15N2OSe)3 crystallizes in the trigonal space group P3. The cell parameters are a = 16.697(4), c = 8.557(8) Å, Z = 2. The structure was solved with Patterson and direct methods and was refined to a final R-value of 4.59%. CoIII is bidentally coordinated to three N,N-diethyl-N′-benzoylselenourea molecules to form a distorted octahedron with facial arrangement of the selenium and oxygen donor atoms. The Co—Se and Co—O bond lengths are 2.328(2) and 1.943(6) Å, respectively. The arrangement of the molecules within the unit cell leads to the formation of hexagonal channels parallel to the crystallographic c-axis. The wall of the channels is formed by carbon atoms of the phenyl group. The diameter of the channels is 8.148 Å.

Die Struktur wurde mit Patterson und Direkten Methoden gelöst und bis zu einem R-Wert von 4,59% verfeinert.

Der Co—Se-Abstand beträgt 2,328(2) Å, der Co—O-Abstand 1,943(6) Å. Die Anordnung der Komplexmoleküle in der Elementarzelle führt zur Ausbildung von hexagonalen Kanälen parallel zur kristallographischen c-Achse. Die Kanalwände werden von Kohlenstoffatomen der Phenylreste gebildet; der Durchmesser der Kanäle beträgt 8,148 Å.

    Description / Table of Contents: A6Nb4S22 (A = Rb und Cs), Verbindungen mit dem tetrameren komplexen Anion [Nb4S22]6-: Darstellung in Alkalimetall-Polychalkogenid-Schmelze und KristallstrukturDie neuen ternären Niob-Polysulfide A6Nb4S22 (A = Rb, Cs) konnten durch eine Reaktion von A2S3 mit Nb-Metall und überschüssigem Schwefel in Form von roten transparenten Kristallen dargestellt werden. Charakteristisch sind hier [Nb4S22]6--Anionen. Zwei Untereinheiten Nb2S10 sind über eine S22--Gruppe verbunden. Nb5+ ist von S22- und S2- als Liganden gemäß [Nb2(μ-η2, η1-S2)(η2-S2)3(S)2]2 (μ-η1-S2)6- umgeben. Die CN ist 6, das Koordinationspolyeder kann als stark verzerrte pentagonale Pyramide beschrieben werden. In der Einheitszelle sind die Anionen stabartig parallel zur b-Achse übereinander gestapelt. Diese Stapel sind in ‚Schichten‘ angeordnet, zwischen denen sich die Alkali-Kationen befinden.
    Notes: The new ternary niobium polysulfides A6Nb4S22 were prepared at a low temperature of 350°C via the molten flux method by reacting A2S3 (A = Rb, Cs) with niobium metal and additional sulfur. The crystal structure is characterized by [Nb4S22]6- anions. Two Nb2S10 subunits are joined by a S22-. Nb5+ is coordinated by S22- and S2- ligands according to [Nb2(μ-η2, η1-S2)(η2-S2)3(S)2]2(μ-η1-S2)6-. Every Nb is in a sixfold coordination, and the polyhedra can be regarded as strongly distorted pentagonal pyramids. Within the unit cell the anions are stacked in “rods” parallel to the crystallographic b-axis. These stacks are arranged in “layers” and the A+ ions are located between the layers.
