    Notes: A prominent reduction of the layer thickness, d1, in the Sm A and Sm B phases with increasing temperature has been observed for a series of side chain polymers. The maximum decrease in d1 value for one of the copolymers is ∼7Å; i.e. 15% of its total value. The influence of the chemical structure of the main chain and side groups on the effect has been studied. Models have been proposed for packing of mesogenic side groups at different temperatures.

    Notes: Substituted poly(methylsiloxane)s connected by a spacer with a biphenyl system that is esterificated with a chiral α-chlorocarboxylic acid have been synthesized and characterized. Their liquid crystalline properties have been studied by differential scanning calorimetry (DSC), polarization microscopy, electro-optical methods and X-ray diffraction. Most of the synthesized compounds and polymers have liquid crystalline phases, mainly smectic phases.

    Description / Table of Contents: Ba5[CrN4]N: The First Nitridochromate(V)Ba5[CrN4]N is prepared by reaction of mixtures of Li3N, Ba3N2 and CrN/Cr2N (1 : 1) (molar ratio Li : Ba : Cr = 3 : 5 : 1) in tantalum crucibles at 700°C with flowing nitrogen (1 atm) within a period of 48 h. After cooling down to room temperature (60°C/h) black-shining single crystals of the ternary phase with a platy habit are obtained (monoclinic, C2/m; a = 1054.0(2) pm, b = 1170.9(3) pm, c = 937.7(2) pm, b̃ = 110,79(2)°; Z = 4). The crystal structure contains isolated complex anions [CrVN4]7- which nearly satisfy the ideal tetrahedral symmetry (Cr—N [pm]: 2 × 175.3(4), 2 × 175.8(5); N—Cr—N [°]: 106.8(2), 109.5(2), 2 × 109.9(2), 2 × 110,3(2)). The coordination sphere for each of the terminal nitride functions of the complex anions is completed by five neighbouring Ba2+ ions (distorted CrBa5 octahedra). The octahedra are connected via common CrBa2 faces as well as CrBa edges thereby forming condensed tetrameric octahedral groups. The isolated nitride ions which are also present in the crystal structure of Ba5[CrN4]N are in an octahedral environment of Ba2+ ions.The presence of a d1-System (Cr(V)) is confirmed by magnetic susceptibility data.
    Notes: Ba5[CrN4]N wird durch Umsetzung von Mischungen aus Li3N, Ba3N2 und CrN/Cr2N (1 : 1) im molaren Verhältnis Li: Ba: Cr = 3 : 5 : 1 bei 700°C im Tantaltiegel unter strömendem Sticksktoff (1 atm) dargestellt. Die Reaktionszeit beträgt 48 h. Nach Abkühlen auf Raumtemperatur (60°C/h) liegt die ternäre Phase in Form schwarz-glänzender Kristalle mit plattigem Habitus vor (monoklin, C2/m; a = 1054,0(2) pm, b = 1170,9(3) pm, c = 937,7(2) pm, b̃ = 110,79(2)°; Z = 4). Die Kristallstruktur enthält isolierte komplexe Anionen [CrVN4]7- mit nahezu idealer Tetraedersymmetrie (Cr—N [pm]: 2 × 175,3(4), 2 × 175,8(5); N—Cr—N [°]: 106,8(2), 109,5(2), 2 × 109,9(2), 2 × 110,3(2)). Die Koordinationssphäre der terminalen Nitrid-Funktionen der komplexen Anionen wird durch je fünf benachbarte Ba-Ionen zu verzerrten CrBa5-Oktaedern vervollständigt. Je zwei dieser Oktaeder sind über gemeinsame CrBa2-Flächen zu dimeren Einheiten verknüpft, die über gemeinsame CrBa-Kanten zu tetrameren Oktaedergruppierungen kondensiert sind. Die in der Kristallstruktur von Ba5[CrN4]N zusätzlich enthaltenen, isolierten Nitridionen sind oktaedrisch von Barium umgeben.Das Vorliegen eines d1-Systems (Cr(V)) wird durch Messungen der magnetischen Suszeptibilität belegt.

    Description / Table of Contents: The Crystal and Molecular Structure of Jodo-bis-[2-(diphenylphosphinomethyl)pyridine]nickel(II)-jodide, which is a Diamagnetic, Square-pyramidal Complex with d8-ConfigurationThe crystal and molecular structure of the title compound has been determined by single-crystal X-ray methods with 5119 independent reflextions and refined to R = 0.061 for 4321 observed reflections. The crystals are monoclinic, space group P21/n, a = 9.016 ± 0.005, b = 21.612 ± 0.012, c = 17.871 ± 0.010 Å, with and β = 96.32 ± 0.15°; Z = 4. The structure was solved by PATTERSON and FOURIER methods and refined by least squares.The molecule cation has approximate Cs-symmetry. The co-ordination around the nickel atom is approximate square pyramidal with two nitrogen and two phosphorus atoms in the basal plane and the jodine atom in the apex. The Ni—J-distance with 3.047(3) Å is very long. In the basal plane, the nitrogen and phosphorus atoms have cis configuration and the geometric arrangements by the two chelate-5-rings are different. The mean Ni—N(1.963(13)Å) and Ni—P(2.166(5)Å) bond lengths are considerably 0.05 longer and 0.10 Å shorter respectively than the corresponding covalent bonding values, derived from the sum of the covalent radii.
    Notes: Die Kristall- und Molekülstruktur der im Titel genannten Verbindung wurde durch eine Röntgenstrukturanalyse an Einkristallen unter Verwendung von 5119 unabhängigen Reflexintensitäten ermittelt. Der R-Wert bei Abschluß der Verfeinerung beträgt für 4321 beobachtete Reflexe 0,061. Die Verbindung kristallisiert in der monoklinen Raumgruppe P21/n mit den Gitterdimensionen a = 9,016 ± 0,005, b = 21,612 ± 0,012, c = 17,871 ± 0,010 Å, β = 96,32 ± 0,15° und 4 Formeleinheiten pro Elementarzelle. Zur Lösung der Struktur wurden PATTERSON- und FOURIER-Synthesen ausgeführt, die Verfeinerung erfolgte durch Kleinste-Quadrate-Berechnungen.Das Molekülkation hat, vereinfachend betrachtet, eine Cs-Pseudosymmetrie. Die Koordination des Nickelatoms ist angenähert als quadratisch-pyramidal mit zwei Stickstoff und zwei Phosphoratomen in der Basisfläche und einem Jodatom in der Spitze aufzufassen. Der Ni—J-Abstand mit 3,047(3) Å ist sehr lang. In der Basisfläche besitzen die Stickstoff und Phosphoratome cis-Konfiguration. Die beiden Chelat-5-Ringe haben unterschiedliche geometrische Gestalt. Die mittleren Ni—N-(1,963(13) Å) und Ni—P-(2,166(5) Å) Bindungsabstände sind 0,05 Å länger bzw. 0,10 Å kürzer als die entsprechenden kovalenten Bindungsabstände, die sich aus der Summe der Kovalenzradien ergeben.
