    Description / Table of Contents: Trigonal Planar CuX3-Groups in Cu2Mo6X14, X = Cl, Br, ICu2Mo6Cl14 (I), Cu2Mo6Br14 (II) and Cu2Mo6I14 (III) were synthesized by thermal treatment of corresponding mixtures of copper(I) and molybdenum(II) halides. The crystal structures were determined by single crystal X-ray analyses. I and II show isotypism, cubic, Pn3 (no. 201, sec. setting), Z = 4, I: a = 12.772(3) Å, II: a = 13.350(2) Å. III shows a new structural type, orthorhombic, Pbca (No. 61), Z = 4, a = 16.058(3) Å, b = 10.643(2) Å, c = 16.963(3) Å. Trigonal planar CuX3 units were found in I—III. Structural behaviour relations are discussed, especially with regard to ionic conductivity.
    Notes: Cu2Mo6Cl14 (I), Cu2Mo6Br14 (II) und Cu2Mo6I14 (III) wurden durch thermische Behandlung der Gemenge der binären Halogenide CuX und Mo6X12 im molaren Verhältnis 2:1 in einkristalliner Form erhalten. Röntgenographische Strukturbestimmung wurde an Einkristallen durchgeführt. I und II zeigen Isotypie, Pn3 (Nr. 201, sec. setting) Z = 4, I: a = 12,772(3) Å, II: a = 13,350(2) Å. III weist eigenen Strukturtyp auf: Pbca (Nr. 61), Z = 4, a = 16,058(3) Å, b = 10,643(2) Å, c = 16,963(3) Å. In I—III liegen trigonal planare CuX3-Gruppen vor. Bindungsverhältnisse und Meßergebnisse der Ionenleitfähigkeit werden diskutiert.

    Description / Table of Contents: AgPbOBr  -  a New Sillén Type? Preparation and Crystal StructureAgPbOBr was prepared for the first time. Its crystal structure was explored by single crystal X-ray diffraction. AgPbOBr crystallizes with tetragonal symmetry in space group P 4/nmm - No. 129 with a = 3.891(1) Å, c = 11.07(1) Å and two formulas per unit cell. Least squares refinement yields an weighted R-value of 0.065. AgPbOBr shows a layered structure with components of the crystal structure of red PbO as well as AgBr. Emphasized differences between the crystal structures of AgPbOBr and the X2-types after Sillén's notation [1] are characteristic. AgPbOBr is the first member of a new structure type, arranged between Sillén- and Aurivilliusphases [2].
    Notes: AgPbOBr wurde erstmalig dargestellt und die Kristallstruktur an Einkristallen aufgeklärt. Es kristallisiert tetragonal (Raumgruppe P4/nmm  -  No. 129) mit a = 3,891(1) Å, c = 11,07(1) Å und z = 2. Die Verfeinerung (LSQ) der Einkristallmessung liefert Rw = 0,065. AgPbOBr ist schichtförmig aufgebaut mit aus PbO und AgBr bestehenden Bereichen, die nahezu unverändert dem Bau von PbO und AgBr gleichen. Die Unterschiede zur Kristallstruktur der Sillén-Phasen vom X2-Typ [1] sind charakteristisch. AgPbOBr nimmt kristallchemisch eine Stellung zwischen den Sillén- und den Aurivillius-Phasen [2] (z. B. BiOCl und γ-Bi2 WO6) ein.

    Description / Table of Contents: HgPb2O2Cl2, a “Perforated” Lead(II) OxideSingle crystals of HgPb2O2Cl2 were grown in a HgCl2 flux by reaction of PbO with HgCl2. Crystal structure analysis by single crystal X-ray methods were carried out. HgPb2O2Cl2 crystallizes monoclinic with a = 11.788(2) Å, b = 3.910(1) Å, c = 7.749(2) Å, β = 122.64(3)°, space group C2/m (No. 12) and Z = 2. HgPb2O2Cl2 is the first member of a new structure type, closely related to the structure of PbO.

HgPb2O2Cl2 kristallisiert monoklin mit a = 11,788(2) Å, b = 3,910(1) Å, c = 7,749(2) Å, β = 122,64(3)°, Raumgruppe C2/m (Nr. 12) und Z = 2. HgPb2O2Cl2 ist der erste Vertreter eines neuen Strukturtyps, der kristallchemisch von der Struktur von PbO ableitbar ist.

    Description / Table of Contents: Preparation and Crystal Structure of Cs2HgPdCl6, a Distorted Variant of ChloroperovskitsCs2HgPdCl6 single crystals show tetragonal symmetry with the space group I 4/m m m (No. 139) with 2 formular units per unit cell. The lattice parameters are a = 7.432(4) Å, c = 10.874(7) Å. The atomic arrangement of Cs2HgPdCl6 is explored by X-ray crystal structure analysis. The important polyhedrons are square-planar PdCl4 groups and HgCl2 dumbbells. The PdCl4 group is completed by two further chlorine atoms to a elongated octahedron and four further chlorine atoms form with the HgCl2 dumbbell a compressed octahedron. The crystal structure of Cs2HgPdCl6 is compared with the arrangement in halogenoperovskits and in Rb2PdCl4 [3].
    Notes: Die Verbindung Cs2HgIIPdIICl6 läßt sich durch Festkörperreaktion phasenrein darstellen. Sie kristallisiert in der Raumgruppe I 4/m m m (No. 139) mit a = 7,432(4) Å, c = 10,874(7) Å, Z = 2. Die Kristallstruktur wurde mit röntgenographischen Methoden an Einkristallen ermittelt. Pd2+ ist quadratisch-planar und Hg2+ hantelförmig von Cl-umgeben. In zweiter Nachbarschaft ergänzen weitere Cl- zu gestreckten bzw. gestauchten Oktaedern. Dieses Bauprinzip entspricht dem Aufbau von Cs2AuIAuIIICl6 [1, 2]. Es besteht direkte kristallchemische Beziehung zur Kristallstruktur der Halogenoperowskite bzw. des K2PdCl4-Typs.

    Description / Table of Contents: Pb2PdX6 (X = Cl, Br) - Compounds with Elongated [PdX6] OctahedraIn contradiction to published data new compounds in the systems PbX2 - PdX2 (X = Cl, Br) with the formula Pb2PdCl6 (I) and Pb2PdBr6 (II) were found. These were synthesized by thermal treatment of the corresponding mixtures of PbX2 and PdX2 (X = Cl, Br). X-ray single crystal structure analysis shows isotypism of I and II, monoclinic, P21/c (No. 14), Z = 2, I: a = 9.037(2) Å, b = 6.224(1) Å, c = 8.162(1) Å, β = 90.31(7)β, II: a = 9.512(7) Å, b = 6.584(8) Å, c = 8.383(3) Å, β = 90.07(5)º. Strongly elongated PdX6 octahedra are found in the crystal structure. Additional characterisation of the compounds was done by DTA, IR/RAMAN spectra and 207Pb MAS NMR investigations. Remarcable low field shifts were found for 207Pb.
    Notes: Entgegen Literaturangaben wurden in den Systemen PbX2 - PdX2 (X = Cl, Br) die neuen Verbindungen Pb2PdCl6(I) und Pb2PdBr6(II) aufgefunden. Sie wurden durch thermische Behandlung der binären Halogenide PbX2 und PdX2 im molaren Verhältnis 2:1 dargestellt (Einkristalle). Die Kristallstrukturen wurden mit Einkristallröntgenuntersuchungen ermittelt. I und II sind isotyp, monoklin, P21/c (Nr. 14), Z = 2, I: a = 9,037(2) Å, b = 6,224(1) Å, c = 8,162(1) Å, β = 90,31(7)º, II: a = 9,512(7) Å, b = 6,584(8) Å, c = 8,383(3) Å, β = 90,07(5)º. In Pb2PdX6 werden stark gestreckte PdX6-Oktaeder beobachtet. Die Verbindungen wurden außerdem mittels DTA, IR/RAMAN-Spektren und 207Pb-MAS-NMR-Untersuchungen charakterisiert. Für 207Pb wurde eine bemerkenswerte Tieffeldverschiebung beobachtet.
