1,3-Bis(4-ethoxyphenyl)triazenido silver(I) (1) is obtained from equimolar amounts of the triazenido anion and AgNO3 in THF/CH3CN. 1 forms in pyridine the dimer [Ag(EtOC6H4NNNC6H4OEt)·py]2 (2) which crystallizes as yellow pyridine solvate 2·2 py in the monoclinic space group P21/n and a = 1067.1(7), b = 1764.5(9), c = 1373.0(9) pm, β = 106.46(7)°, Z = 2. In the centrosymmetric dimer 2, two triazenido ligands bridge two Ag(I) atoms with their atoms N1 and N3 forming an eight-membered heterocycle Ag2N6 with a short Ag-Ag interaction of 272.6 pm. To each Ag atom an additional pyridine ligand is weakly coordinated with a distance Ag-N40 = 245.5 pm. The bond axis N1 - Ag-N3′ within the heterocycle is not linear (158.5°). The Ag-N distances to the N-atoms of the triazenido ligand are 217.6 and 218.5 pm.

Abstract(Cp)Mo(CO)2(tolN5tol) is formed in the reaction of (Cp)Mo(CO)3Cl with tolNN(NH)NNtol and NaOH in ethanol. It forms red platelike crystals from THF/hexane which crystallize in the monoclinic space group P21/n with the lattice parameters a = 765.6(2), b = 2372.3(3), c = 1149.4(2) pm, β = 97.06(2)°, Z = 4. The structure consists of monomeric complexes. The pentaazadienido ligand chelates with its nitrogen atoms N1 and N3 the Mo atom of a (Cp)Mo(CO)2 unit. The nitrogen atom N5 is not coordinated to the metal atom. Although asymmetrically bonded, the all trans N5 zig zag chain is planar. The N -N distances in the four membered chelate ring are nearly equal (N1 - N2 = 131.0 and N2 - N3 = 132.6 pm)

The One

The title compound, tetrasodium heptanickel hexaarsenate, was obtained by ceramic synthesis and crystallizes in the monoclinic space groupC2/m. The asymmetric unit contains seven Ni atoms of which two have site symmetry 2/mand three site symmetry 2, four As atoms of which two have site symmetrymand two site symmetry 2, three Na atoms of which two have site symmetry 2, and fifteen O atoms of which four have site symmetrym. The structure of Na4Ni7(AsO4)6is made of layers of Ni octahedra and As tetrahedra assembled in sheets parallel to thebcplane. These layers are interconnected by corner-sharing between NiO6octahedra and AsO4tetrahedra. This linkage creates tunnels running along thecaxis in which the Na atoms are located. This arrangement is similar to the one observed in Na4Ni7(PO4)6, but the layers of the two compounds are slightly different because of the disorder of one of the Ni sites in the structure of the title compound.

Bis(phthalocyaninato(2-)iridium(II)) reacts in methanol with excess tetra(n-butyl)ammonium hydroxide to yield tetra(n-butyl)ammonium hydroxomethoxophthalocyaninato(2-)iridate(III). The complex salt crystallizes as a methanol solvate in the monoclinic space group P21/n(No. 14) with cell parameters a = 12.510(1) Å, b = 19.561(3) Å, c = 18.489(2) Å, = 90.42(1) °, Z = 4. The Ir atom is hexacoordinated with four isoindole N atoms ( N iso ) of the severely saddled pc ligand and two O atoms of the hydroxide ( O 1) and methoxide ( O2 ) ligand respectively in a mutual trans arrangement. The average Ir-N iso distance is 1.981(5) Å, the Ir-O1 distance 2.038(7) Å and the Ir-O2 distance 2.061(6) Å. The O atom of the solvate ( O3 ) is bound to O2 by a strong hydrogen bond with an O2 - O3 distance of 2.60(1) Å.

The unit cell of N-tert-butyl-3-(tert-butylimino)-2-nitropropen-1-amine (4) is monoclinic, space group P21/C, with a = 9.669(4), b = 16.415(6), c = 17.341 (7) Å, and Z = 4. Hydrolysis of 4 leads to (E)-3-(N-tert-butylamino)-2-nitro-2-propenal (5), whose unit cell is monoclinic, space group P21/n, with a = 6.821(1), b = 20.707(6), c = 6.303(1)Å, and Z = 4. Compounds 4 and 5 both possess C2 symmetry in the solid state, their “U-shaped” conjugated cores being essentially planar. In each case this planarity is enforced by an intramolecular hydrogen bond.

Reported are the synthesis and crystal structure of Ba7Li11Bi10, a new ternary compound crystallizing in its own type with the monoclinic space group C2/m (a = 18.407(3) Å, b = 5.0258(9) Å, and c = 18.353(3) Å; β = 104.43(1)°; Pearson symbol mS56), and those of the structurally related quaternary phases Ba4(Li1−xGax)7Sb6, Ba4(Li1−xInx)7Sb6, Ba4(Li1−xInx)7Bi6, and Eu4(Li1−xInx)7Bi6 (crystallizing in the Eu4Li7Bi6 structure type with the same monoclinic space group C2/m (a = 18.4045(13)–17.642(4) Å, b = 5.012(4)–4.8297(10) Å, and c = 13.2792(10)–12.850(3) Å, β = 126.80(1)–125.85(1)°; Pearson symbol mS34). All studied compounds are identified among the products of the high-temperature reactions of the corresponding elements. Both types of crystal structures are based on corner- and edge-linked Li-centered Sb4 (or Bi4) tetrahedra, Sb6 (or Bi6) octahedra, and Sb2 or Bi2 dumbbells. Given the similarities between the two structures, it might be proposed that they represent the simplest members of a potentially large homologous series described with the general formulae (BaLi3Sb2)n(Ba3Li4Sb4)m or (BaLi3Bi2)n(Ba3Li4Bi4)m, where the more complicated “7-11-10” phase is the member with n = 2 and m = 1, while the “4-7-6” one is the intergrowth of the two components in an equal ratio. The computed electronic band structures of Ba7Li11Bi10 and idealized Ba4Li7Bi6 (a model for Ba4(Li1−xInx)7Bi6) are also discussed.

Phthalocyaninato(2–)iridate(I) is oxidized by air in acetone to form acetonato(C)chlorophthalocyaninato(2–)iridate(III) in the presence of chloride. The anion is isolated as its 2,4,6-triphenylpyrylium salt, ( TPPy )[ Ir ( aC )( Cl ) Pc 2−]. Its monohydrate crystallizes in the monoclinic space group P1n1 (#7). The cell parameters are a = 12.452(3) Å, b = 12.339(3) Å, c = 15.352(4) Å, β = 100.75(2) °, Z = 2. Hexa-coordinated Ir is located slightly out of the centre (ct) of the Pc core (d( Ir-ct ) = 0.02 Å) and directed towards the acetonato C atom. It coordinates four isoindole N atoms ( N iso ) together with a Cl atom and a C-bonded acetonate in a mutual trans position. The average Ir – N iso distance is 1.966 Å;, the Ir – Cl distance is 2.501(5) Å; and the Ir –C distance is 2.11(2) Å.

Single crystals of the compound α -Zn3(BO3)(PO4) were obtained at 1050 °C by using B2O3, P2O5 and ZnCO3 as starting materials and subsequent cooling to 600°C with 20°C/h. X-ray investigations on single crystals yield a new crystal structure in the monoclinic space group Cm - (Nr. 8) with a = 972.5(2); b = 1272.0(3); c = 487.4(3) pm; β = 119.80 (4)°; Z = 4. The structure contains isolated trigonally planar BO3 and tetrahedral PO4 units which are not joined together. Zinc occupies three crystallographically different point positions and is trigonal-bipyramidally, tetragonal-pyramidally or distorted tetrahedrally coordinated by oxygen
