    Notes: One hundred ASA grade 1 and 2 patients requiring orotracheal intubation for various general surgical procedures were randomly assigned to receive either expert rigid laryngoscopic or novice fibreoptic orotracheal intubation under total intravenous anaesthesia. Five anaesthesia residents in the 4th year, with no prior experience in fibreoptic laryngoscopy, participated in a fibreoptic training course, viewing two instructional videos and practising on the intubation manikin. Each resident intubated 20 patients in a randomised fashion either as an expert laryngoscopist or as a fibreoptic novice. The time (SEM) to achieve successful intubation was statistically different for fibreoptic and rigid intubation (77.2 (5.1) s vs 17.7 (1.6) s, p 〈 0.01). The time to achieve successful rigid laryngoscopic intubation remained constant over the ten intubations, whereas time required for fibreoptic intubation decreases significantly (p 〈 0.01). The learning objectives (fibreoptic intubation times in 60 s or less and with 90% or greater success rate on the first intubation attempt) were met by all residents. The haemodynamic profile was similar for fibreoptically intubated and conventionally intubated patients and there was no difference between the first two or the last two fibreoptive or rigid intubations. The study was designed to detect a difference of 10% in means (assuming β= 0.05 and 0.2). The incidence of postoperative sore throat, dysphagia or hoarsensess was similar in both groups. We conclude that routine fibreoptic orotracheal intubation in ASA grades 1 and 2 surgical patients is justifiable for teaching this valuable technique. since it increases clinical exposure to fibreoptic intubation, which should be learned and mastered by all anaesthetic residents by completion of their residency.

    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.
    Notes: Einkristalle von HgPb2O2Cl2 wurden durch Umsetzung von PbO und HgCl2 in HgCl2-Schmelzen gezüchtet. An ihnen wurde der Aufbau mittels Einkristallröntgenstrukturanalyse bestimmt. 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: 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: 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: 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.
