    Notes: Abstract Using a208Pb beam of the UNILAC accelerator at GSI we produced the new isotopes203Au and205Au and identified them by measuring theirβ-decay properties. Their half-lives were found to be 60(6)s and 31(2)s, respectively, and theQ-value of203Au was determined to beQ β =2040(60)keV. Nuclear structure information of203,205Hg was derived from this measurement. Furthermore, production cross-sections of203,205Au are given and compared to those obtained in other experiments.

    Notes: Abstract With a summation-free β+-endpoint spectrometer the β+-decay energies of104Sn,147Tb,148, 149Dy,149Ho,150Er, and151Tm were remeasured with improved accuracy. Combined with known proton and alpha decay energies, the resulting QEC values lead to atomic masses of very neutron-deficient isotopes including nuclei beyond the proton drip-line such as109I and113Cs. Furthermore, the Gamow-Tellerβ-strength of the even-even nuclei104Sn,148Dy, and150Er is reevaluated with reduced uncertainty.

    Notes: Es werden die RAMAN-Spektren von Trimethyl-, Tri-dimethylamino-, Trimethoxy-, Trichlor-boroxol und von B-Trimethylborazol mitgeteilt. Die Diskussion der spektralen Daten erbringt in Anlehnung an die gut untersuchten Spektren von 1,3,5-trisubstituierten Benzolen den sicheren Nachweis für einen ebenen Sechsring B3O3 in allen Boroxolverbindungen. Dieser liegt nach dem RAMAN-Spektrum auch im Dibortrioxyd vor.

    Description / Table of Contents: About Ag6(SO4)(SiO4)Hitherto unknown Ag6(SO4)(SiO4) has been prepared at 400-500°C under an oxygen pressure more than 1000 atm. By single crystal X-ray work the structure of tetragonal Ag6(SO4)(SiO4) has been elucidated: a = 7.060, c = 17.660 Å; D4h19-141/amd; Z = 4. The crystal structure shows a new type in which the tetrahedrally sulfat- and silicat groups are definite distinguishable. As well the both crystallographic silver positions show a different crystal-chemical character.
    Notes: Neu dargestellt wurde Ag6(SO4)(SiO4) bei 400-500°C unter einem Sauerstoffdruck größer als 1000 atm. Nach röntgenographischen Untersuchungen der rubinroten Einkristalle kristallisiert die Verbindung tetragonal: a = 7,060, c = 17,660 Å; D4h19-141/amd; Z = 4. Die Kristallstruktur von Ag6(SO4)(SiO4) stellt einen neuen Strukturtyp dar, worin die tetraedrischen Sulfat- und Silicatgruppen deutlich unterscheidbar sind. Ebenso weisen die beiden kristallographischen Silberpositionen verschiedenartige kristallchemische Charaktere auf.

    Description / Table of Contents: Crystal Structure of Tl3PbCl5Single crystals of the compound Tl3PbCl5 were prepared. Tetragonal symmetry with the lattice parameters a = 844.8 pm, c = 1 491.2 pm was shown by X-ray investigations. Tl3PbCl5 belongs to the space group P41 (No. 76). The crystal structure was solved by MULTAN and refined till R = 0.050. The metal particles are surrounded by seven chloride ions. This polyhedras are connected in a 3-dimensional way. Tl3PbCl5 shows a new structure type, without any constitutional relations to Cs3CoCl5 or (NH4)3ZnCl5.
    Notes: Die Verbindung Tl3PbCl5 wurde in Einkristallen dargestellt und röntgenographisch untersucht. Die Kristalle zeigen tetragonale Symmetrie mit a = 844,8 pm, c = 1 491,2 pm und sind der Raumgruppe P41 (No. 76) zuzuordnen. Die Kristallstruktur wurde mit MULTAN bestimmt und bis zu einem R-Wert von 0,050 verfeinert. Die Thallium- und Bleiteilchen sind von sieben Chloridionen umgeben. Die Koordinationspolyeder sind untereinander dreidimensional verknüpft. Tl3PbCl5 kristallisiert in einem neuen Bautyp, der keinerlei strukturelle Beziehung zu Cs3CoCl5 oder (NH4)3ZnCl5 zeigt.

    Description / Table of Contents: Crystalline Adducts of 7, 7, 8, 8-Tetracyanoquinodimethane (TCNQ) with Bis(1,2-benzoquinonedioximato)nickel(II) and palladium(II): Synthesis and StructureSolid adducts of stoichiometry Ni(BCD)2 · TCNQ and Pd(BCD)2 · TCNQ were obtained by reacting bis(1,2-benzoquinonedioximato)nickel(II) and palladium(II) with TCNQ. The compound Pd(BCD)2 · TCNQ crystallizes in the triclinic space group P1 with cell parameters a = 10.251(3) Å, b = 7.843(3) Å, c = 7.328(2) Å, α = 105.54° (3), β = 83.63° (3), γ = 92.28° (3), Z = 1, Dx = 1.72 g · cm-3. The structure was solved by standard Patterson and Fourier methods and refined by the least squares technique to a R-value of 6.4% based on 2230 observed independent reflexions. The structure consists of parallel stacks of alternating TCNQ and Pd(BCD)2 molecules which are planar and electrically neutral. The normals of the molecular planes are inclined with respect to the stacking direction.
    Notes: Bei der Reaktion von Bis(1,2-benzochinondioximato)-nickel(II), [Ni(BCD)2] und -palladium(II), [Pd(BCD)2] mit TCNQ wurden die kristallinen Addukte Ni(BCD)2 · TCNQ und Pd(BCD)2 ·TCNQ erhalten. Die beiden Verbindungen sind isomorph und kristallisieren in der triklinen Raumgruppe P1. Die Struktur der Palladiumverbindung (a = 10,251(3) Å, b = 7,843(3) Å, c = 7,328(2) Å, α = 105,54°(3), β = 83,63°(3), γ = 92,28° (3), Z = 1, Dx = 1,72 g·cm-3) wurde mittels Patterson- und Fouriersynthesen bestimmt. Die Verfeinerung nach der Methode, der kleinsten Quadrate lieferte mit allen 2 230 beobachteten unabhängigen Reflexen einen R-Wert von 6,4%. Die Struktur besteht aus parallelen Stapeln von sich abwechselnden TCNQ- und Pd(BCD)2-Molekülen, die eben und ungeladen sind. Die Normalen der Molekülebenen sind zur Stapelrichtung geneigt.
