    Notes: Summary Three adducts of zinc azide with 2,4-/3,4- and 3,5-dimethylpyridine (DMP), respectively, were prepared and the crystal structures determined by single crystal X-ray diffraction methods. The three compounds crystallize in the monoclinic space group P21/c withZ=4: Zn(N3)2·2,4-DMP at 300 (2) K:a=1 098.6(4),b=1 600.2(6),c=608.8(3) pm, β=102.47(3)°;R=0.071 (R w =0.056). Zn(N3)2·3,4-DMP at 103 (3) K:a=1 102.1(3),b=1 649.0(4),c=611.8(1) pm, β=104.54(2)°;R=0.055 (R w =0.051). Zn(N3)2·3,5-DMP at 97 (3) K:a=602.1(2),b=2 037.9(7),c=853.8(3) pm, β=90.77(3)°;R=0.069 (R w =0.055). The molecular geometry is similar for the three adducts, but the packing of theDMP-molecules is different. The zinc atoms are surrounded by five nitrogen atoms, four belonging to the azide groups and one to theDMP-adduct. The trigonal bipyramidal shaped ZnN5-polyhedra share common edges to form chains.

    Notes: Abstract Cs2[Co3(N3)8] crystallizes monoclinic,a=1 123.8 (3),b=568.4 (2),c=1 542.6 (4) pm, β=107.37 (2)°, space group P21/n,Z=2. The crystal structure was determined by single crystal X-ray diffraction,R w=0.069. Coatoms are coordinated octahedrally to six azide groups and form polynuclear complexes of composition [Co3(N3)8]2−. The complex anions share edges and are connected to infinite chains running along theb-axis direction. Cesium is irregularly surrounded by azide groups.

    Notes: Summary The crystal structure of dicesium-tetraazido-zincate, Cs2Zn(N3)4, has been refined from single crystal X-ray-diffractometer data. The previously reported orthorhombic structure, consisting of isolated Zn(N3)4-tetrahedra was confirmed and improved lattice parameters and atomic distances were determined. The azide groups are asymmetric and the coordination of central nitrogen atoms to cesium was observed. A table of structure data and mean atomic distances for fourteen zinc-azide compounds is added and the structures are discussed.

    Notes: Abstract Single crystals of Ca(N3)2·2 H2O have been prepared from aqueous solutions at room temperature. The crystals are monoclinic,a=1 159.0 (3),b=614.2 (2),c=785.5 (2) pm, β=106.52 (2)°,Z=4, space group P21/n. The crystal structure was determined by single crystal X-ray diffraction (1 109 Mo-Kα-reflexions,R=0.052). Calcium atoms are surrounded by four azide groups and four water molecules. The coordination polyhedra are antiprism which are sharing azide groups and water molecules to form layers. The lattice constants and powder pattern agree well with values reported earlier for Ca(N3)2 · 1.5 H2O [1]. It was also shown, that Sr(N3)2 · 2 H2O is isotypic with Ca(N3)2 · 2 H2O.

    Description / Table of Contents: Zusammenfassung Die Temperaturabhängigkeit der Gitterparameter und die Atomlagen der Tieftemperaturphase von SrMo6S8 wurden mittels Röntgenpulverdiffraktometrie bestimmt. Die rhomboedrische Hochtemperaturmodifikation (R $$\bar 3$$ ,a rh=6.5630(3)Å, αrh=88.9982(2)°,V rh=282.55(5)Å3,T=298 K) wandelt beiT 1=135(3) K in die trikline Tieftemperaturmodifikation (P $$\bar 1$$ ,a tr=6.481(1)Å,b tr=6.572(1)Å,c tr=6.611(1)Å, αtr=89.246(4)°, βtr=89.304(4)°, γtr=88.169(4)°,V tr=281.4(2)Å3,T=20 K) um. Die trikline Deformation ist stärker ausgeprägt als in der Ca-Verbindung und ähnlich jener der Ba- and Eu-Verbindung.
    Notes: Abstract Lattice parameters as a function of temperature for, and atomic coordinates of the low-temperature phase of, SrMo6S8 are reported from X-ray powder diffraction. The structure transforms atT 1=135(3) K from the rhombohedral high-temperature modification (R $$\bar 3$$ ,a rh=6.5630 (3) Å, αrh=88.9982(2)°,V rh=282.55(5)Å3 at 298 K) into the triclinic low-temperature modification (P $$\bar 1$$ ,a tr=6.481(1)Å,b tr=6.572(1)Å,c tr=6.611(1)Å, αtr=89.246(4)°, βtr=89.304(4)°, γtr=88.169(4)°,V tr=281.4(2)Å3 at 20K). The triclinic distortion is larger than in the Ca analogue, and similar to the Ba and Eu analogues.

    Notes: Summary The crystal structure of pentacesium octaazidoeuropiate(III), Cs5Eu(N3)8, was determined by single crystal X-ray diffraction: orthorhombic,a=16.811(4),b=16.860(5),c=16.964(3)Å, space group Pbca,Z=8, 2 310 observed reflections,R=0.048. Europium atoms are coordinated to eight azide groups, the coordination polyhedra have no azide groups in common. Four cesium atoms are surrounded by eight, one by seven azide groups. The azide groups are symmetric with mean N-N-distances of 1.17(1)Å.

    Notes: Abstract A mixed ligand 1∶2 complex of copper(II) azide with 3,5-lutidine, namely di-μ(1,1)-azido-diμ(0,0)-nitrato)tetrakis(3,5-lutidine)dicopper(II) has been prepared and characterized by X-ray crystallographic and spectroscopic methods. The dimeric molecule, which possesses a crystallographic inversion center, contains twoμ(1,1) bridging azido ligands. Each copper(II) atom in the cyclic Cu2N2 unit is further coordinated by two oxygen atoms from twoμ(0,0-nitrato) bridges at Cu-O distances of 2.465(3) and 2.568(3) Å and two nitrogen atoms from the lutidine molecules [Cu-N=2.003(3) and 2.012(3) Å] to give a distorted tetragonal bipyramid. Both azido ligands are linear [N-N-N angle=179.0(4) and asymmetric Nα-Nβ=1.207(4) and Nβ-Nτ=1.135(5) Å]. The azido bridges produce a rather short Cu ⋯ Cu distance of 3.013(2) Å. Infrared and electronic data are presented and discussed.

    Notes: Abstract A new series of CoL4(N3)2 complexes (L = 4-Et, 4-PhCO and 3-hydroxypyridine) has been prepared and characterized and their i.r. and electronic spectra is reported and discussed. The structure of Co(4-benzoylpyridine)4(N3)2, as determined by X-ray crystallography, consists of discrete monomers molecules with a trans-six-coordinated cobalt(II) environment. The terminal azides are almost linear and asymmetric within the experimental error.

    Notes: Abstract Two new 1:2 polymeric complexes of copper(II) azide with ethyl isonicotinate (1) and methyl isonicotinate (2) have been synthesized and characterized by spectroscopic and crystallographic methods. The polymeric structure of complex (1) features six coordinated copper centers, a pair of trans-coordinated ligand molecules, and asymmetric μ2-1,1 and μ2-1,3-azido bridges resulting in a 1D chain structure. In complex (2), each copper atom which is located at an inversion center, is coordinated to a pair of trans ligand molecules, to the nitrogen atom of two μ-1,1-azido ligand and to an oxygen atom of a bridging (μ-O,O′) nitrogen group. The i.r., electronic and e.s.r. spectra of the complexes are reported.
