    Description: Polynitrogens have the potential for ultrahigh-performing explosives or propellants because singly or doubly bonded polynitrogens can decompose to triply bonded dinitrogen (N2) with an extraordinarily large energy release. The large energy content and relatively low activation energy toward decomposition makes the synthesis of a stable polynitrogen allotrope an extraordinary challenge. Many elements exist in different forms (allotropes)—for example, carbon can exist as graphite, diamond, buckyballs, or graphene. However, no stable neutral allotropes are known for nitrogen, and only two stable homonuclear polynitrogen ions had been isolated until now—namely, the N3− anion (1) and the N5+ cation (2). On page 374 of this issue, Zhang et al. (3) report the synthesis and characterization of the first stable salt of the cyclo-N5− anion, only the third stable homonuclear polynitrogen ion ever isolated. Author: Karl O. Christe

    Description / Table of Contents: Synthesis, Properties, and Structure of LiAuI4 and KAuI4 with a Discussion of the Crystal Chemical Relationship between the Halogenoaurates RbAuCl4, AgAuCl4, RbAuBr4 and LiAuI4The alkalimetal iodo aurates(III) MAuI4 (M = Li, K) are obtained in form of single crystals from MI, Au and I2 in a sealed glass ampoule by heating to 550°C and slow cooling to 300°C. KAuI4 crystallizes in the monoclinic space group P21/c with a = 968.6(4); b = 704.5(2), c = 1393.2(7) pm; β = 100.95(2)° and Z = 4. The crystal structure is built up from square planar AuI4- anions and K+ cations. The cations are coordinated by eight I atoms of neighbouring AuI4- anions with distances K—I between 350.0 and 369.6 pm. At 100°C KAuI4 is reduced to form K3Au3I8, which at 180°C decomposes to KI, Au and I2 LiAuI4 forms black, moisture sensitive needles, decomposing in the absence of iodine at 20°C to LiI, Au and I2. It crystallizes in a variant of the RbAuBr4 type structure with the space group P21/a and a = 1511.7(4); b = 433.9(4); c = 710.0(2) pm; β = 121.50(2)°; Z = 2. The crystal chemical relationship between the structures of RbAuCl4, RbAuBr4, AgAuCl4 and LiAuI4 is discussed.
    Notes: Die Alkalimetalliodoaurate(III) MAuI4 (M = Li, K) entstehen in Form von Einkristallen aus MI, Au und I2 in einer unter Vakuum abgeschmolzenen Glasampulle durch Erhitzen auf 550°C und langsames Abkühlen auf 300°C. KAuI4 kristallisiert monoklin in der Raumgruppe P21/c mit a = 968,6(4); b = 704,5(2), c = 1393,2(7) pm; β = 100,95(2)° und Z = 4. Die Kristallstruktur ist aus quadratisch-planaren AuI4--Anionen und K+-Kationen aufgebaut. Die Kationen sind von acht I-Atomen benachbarter AuI4--Ionen im Abstand von 350,0 bis 369,6 pm umgeben. KAuI4 zersetzt sich bei 100°C in K3Au3I8, das bei 180°C zu KI, Au und I2 zerfällt. LiAuI4 bildet schwarze, hydrolyseempfindliche Kristallnadeln, die sich außerhalb einer Iodatmosphäre bereits bei 20°C in LiI, Au und I2 zersetzen. Es kristallisiert in einer Strukturvariante des RbAuBr4-Typs mit der Raumgruppe P21/a und a = 1511,7(4); b = 433,9(4); c = 710,0(2) pm; β = 121,50(2)°; Z = 2. Die kristallchemische Verwandtschaft zwischen den Strukturen von RbAuCl4, RbAuBr4, AgAuCl4 und LiAuI4 wird diskutiert.

    Description / Table of Contents: Lewis-Acid-Base-Reactions of Gold Trihalides with Bismuth Trihalides - Synthesis and Structures of AuBiX6 (X = CI, Br)Gold trihalides AuX3 (X = Cl, Br) react with bismuth trihalides in sealed glass ampoules to the 1 : 1 adducts AuBiX6 (X = Cl, Br). AuBiCl6 is obtained by a chemical transport reaction at 220°C, whereas AuBiBr6 was synthesized by solvothermal reaction in SiBr4 at 150°C. Both compounds crystallize triclinic, space group P1, Z = 4. AuBiCl6; a = 698.3(4) pm; b = 1009.3(5) pm; c = 1381(1) pm; α = 104.98(5)°; β = 94.73(5)°; γ = 110.06(3)°; V = 867(1) · 106 pm3. AuBiBr6: a = 735.7(4) pm; b = 1055.7(5) pm; c = 1445(1) pm; α =104.88(5)°; β = 94.25(5)°; γ = 110.18(4)°; V =1001(1) ·106pm3. The structures are build formally of square-planar [AuX4]- and chains of edge-connected ([BiX4/2]+)n units. Since each Bi ion is surrounded by eight halogenide ions in a square-antiprismatic form, the structure can alternatively be described as consisting of chains of edge sharing ([BiX4X4/2]3-)n antiprisms connected by Au3+ ions.
    Notes: Goldtrihalogenide AuX3 (X = CI, Br) reagieren mit den entsprechenden Bismuttrihalogeniden BiX3 (X = Cl, Br) in geschlossenen Ampullen zu den 1 : 1-Addukten AuBiX6. AuBiCl6 entsteht bei 220°C unter den Bedingungen des chemischen Transportes, während AuBiBr6 wegen der geringen thermischen Stabilität von AuBr3 unter solvothermalen Bedingungen in SiBr4 als Lösungsmittel bei 150°C dargestellt wurde. Beide Verbindungen sind isotyp und kristallisieren triklin in der Raumgruppe P1, Z = 4, mit den Gitterkonstanten a = 698,3(4) pm; b = 1009,3(5) pm; c = 1381(1) pm; α = 104,98(5)°; β = 94,73(5)°; γ = 110,06(3)° für AuBiCl6 und a = 735,7(4) pm; b = 1055,7(5) pm; c = 1445(1) pm; α = 104,88(5)°; β = 94,25(5)°; γ = 110,18(4)° für AuBiBr6. Die Strukturen sind aus quadratisch-planaren [AuX4]--Ionen und Ketten aus kantenverknüpften ([BiX4/2]+)n-Einheiten aufgebaut. Da die Bi-Ionen von acht Halogenid-Ionen in Form eines quadratischen Antiprismas umgeben sind, kann die Struktur alternativ so beschrieben werden, daß sie aus Ketten kantenverknüpfter ([BiX4X4/2]3- )n-Antiprismen besteht, die über Au3+ -Ionen verbunden sind.

    Description / Table of Contents: Ba11KX7O2 (X = P, As): Zwei neuartige Zintl-Phasen mit unendlichen Ketten sauerstoffzentrierter Ba6-Oktaeder, isolierten X3- und dimeren X24- AnionenReaktionen von „BaX“ (X = P, As) mit elementarem Ba, K und BaO in Tantalampullen bei 900-1000°C ergaben schwarze, sehr luft- und feuchtigkeitsempfindliche Kristalle von Ba11KP7O2 und der dazu isotypen Verbindung Ba11KAs7O2. welche durch EDX und Röntgenbeugung charakterisiert wurden (orthorhombisch, Fddd, Z = 8; a = 1069,9(1), b = 1514,3(2), c = 3164,6(4) pm und a = 1087,8(2), b = 1542,3(2), c = 3232,4(4) pm). In der Struktur liegen parallel zu [100] unendliche Zickzack-Ketten, ∞1[Ba4Ba2/2O], aus eckenverknüpften Ba6-Oktaedern vor, die durch O-Atome zentriert werden. Dazwischen befinden sich lineare Reihen von abwechselnd angeordneten isolierten X-Atomen und X2-Hanteln, welche die Oktaederketten zu Schichten parallel zu (001) miteinander verbinden. Während sich die X-Atome in einem verzerrten Ba8-Würfel befinden, zentrieren die X2-Hanteln einen Ba12-Polyeder, welcher aus einem Paar flächenverknüpfter, quadratischer Ba-Antiprismen aufgebaut ist. Hieraus ergibt sich die Abfolge Würfel-Antiprisma-Antiprisma-Würfel aus flächenverknüpften Ba-Polyedern. Zwischen den Schichten befinden sich weitere isolierte X-Atome und verknüpfen diese entlang [001] miteinander. Zwei Atompositionen sind statistisch mit Ba und K besetzt, so daß nach dem Zintl-Klemm-Konzept die Summenformel der Verbindungen auch durch Ba2+11K+X3-5(X2)4-O2-2 ausgedrückt werden kann.
    Notes: Reactions of “BaX” (X = P, As) with Ba, K and BaO in tantalum tubes at 900-1000°C yielded black, very air- and moisture-sensitive crystals of Ba11KP7O2 and isotypic Ba11KAs7O2 which were characterized by EDX and X-ray diffraction (orthorhombic, Fddd, Z = 8; a = 1069.9(1), b = 1514.3(2), c = 3164.6(4) pm and a = 1087.8(2), b = 1542.3(2), c = 3232.4(4) pm, respectively). The structure contains infinite zigzag chains, ∞1[Ba4Ba2/2O], of oxygen-centered, corner-sharing Ba6 octahedra along [100]. They are connected by linear strings built of alternating isolated X atoms and X2 dimers to form layers parallel to (001). While the isolated X atoms are surrounded by eight Ba forming a distorted cube, the X2 dimers center a Ba12 polyhedron which is comprised of a pair of face-sharing Ba square antiprisms. This results in a cube-antiprism-antiprism-cube sequence of face-sharing Ba polyhedra. Additional X atoms function as spacers between the layers and connect them along [001]. Two atom positions are statistically occupied by Ba and K, and the formula may be written as Ba2+11K+X3-5(X2)4-O2-2 according to the Zintl-Klemm concept.

    Description / Table of Contents: Homoleptic Zinc Amides: Transition to Monomeric MoleculesZinc chloride reacts with the lithium salts of the bulky secondary amines HN(i-Bu)2 and HN(t-Bu)2 to form the corresponding homoleptic zinc compounds {Zn[N(i-Bu)2]2}2 (1) and Zn[N(t-Bu)2]2 (2). The NMR spectroscopic and mass spectrometric results as well as the molecular weight determinations and X-ray diffraction data are consistent with a dimeric structure of 1 and a monomeric structure of 2 in the gas phase, in solution and in the solid state.

Entsprechend der Ergebnisse von NMR-Spektroskopie, Massenspektrometrie, Molmassenbestimmung und Röntgenstrukturanalyse ist 1 dimer, 2 dagegen in der Gasphase, in Lösung und im Festkörper monomer.
