Abstract:
Six new organotin(IV) compounds of Schiff bases derived from S-R-dithiocarbazate [R = benzyl (B), 2- or 4-methylbenzyl (2M and 4M, respectively)] condensed with 2-hydroxy-3-methoxybenzaldehyde (oVa) were synthesised and characterised by elemental analysis, various spectroscopic techniques including infrared, UV-vis, multinuclear (1H, 13C, 119Sn) NMR and mass spectrometry, and single crystal X-ray diffraction. The organotin(IV) compounds were synthesised from the reaction of Ph2SnCl2 or Me2SnCl2 with the Schiff bases (S2MoVaH/S4MoVaH/SBoVaH) to form a total of six new organotin(IV) compounds th

Abstract:
Stannyloligosilanes 1 and 2 with terminal organotin groups are available by reacting alkali metal tri- or diorganostannides with α,ω-dichloro- or difluorosilanes, or by treatment of organochlorostannanes with α,ω-difluorosilanes in the presence of magnesium . Attempts to functionalize the triorganotin derivatives 2 by halogenation reagents did not result in the halogen compounds 5; instead cleavage of silicon-tin bonds is observed. In contrast, reactions of the hydridotin derivatives 1 with CHX3 (X = Cl, Br) lead to the quantitative formation of the bis(chloro- or bromostannyl)oligosilanes 5.

Select bacterial strains survive in mercury-contaminated environments due to acquisition of a transferable genetic element known as the mer operon. The mer operon typically encodes for a series of proteins that includes two enzymes, MerA and MerB. The organomercurial lyase (MerB) cleaves carbon-mercury bonds of organomercurial compounds yielding ionic mercury Hg (II) and a reduced-carbon compound. The Hg (II) ion product remains bounds until it is shuttled directly to the mercuric ion reductase (MerA) to be reduced. Based on NMR spectroscopy and X-ray crystallography studies1, we have determin

Abstract:
Organic frameworks with rigid backbones, such as acenaphthene, are highly suitable for the study of interatomic interactions. The short “natural” peri-distance (2.44 Å) and the rigidity of the aromatic system causes considerable steric strain between peri-substituted heteroatoms. As a consequence, substitution at both peri-positions leads to in- and out-of-plane distortions, which often result in buckling of the ring system. In order to relax this geometric strain, weak bonding interactions can also exist between the peri-substituents. This thesis focuses on the synthesis, structural character

Abstract:
Among the statistics freely available on the webpage of the Cambridge Structural Database, there is a detail of interest for this chapter: of the 596 910 crystal structures deposited up to 1 January 2012, only 1534 were solved by neutron data (see Table 1.11). No information is provided on the number of structures solved by electron data because it is negligible (organic samples are soon damaged by the electron beams). A statistical search of the Inorganic Crystal Structure Database (ICSD, Ver. 2012–1, about 150 000 entries; by courtesy of Thomas Weirich) on structures that have been solved by means of electron diffraction, eventually in combination with other techniques, indicates a total of about 0.7%. In spite of limited impact on the databases, electron and neutron diffraction play a fundamental role in materials science and in crystallography. The main reason is that they provide alternative techniques to X-rays. Let us first consider electron diffraction (ED) techniques. The study of crystalline samples at the nanometer scale is mandatory for many industrial applications; indeed, physical properties depend on the crystal structure. Unfortunately it is not unusual for compounds to only exist in the nanocrystalline state; then, traditional X-ray diffraction techniques for atomic structure determination cannot be applied, because of the weak interactions between X-rays and matter. As a consequence, such structures remain unknown, in spite of their technological importance. This limits the contribution of X-ray crystallography to nanoscience, a growing scientific area, crucial to many fields, from semiconductors to pharmaceuticals and proteins. The result is a lack of knowledge on the underlying structure–property relationships, which often retards further research and development. Structure analysis by electron diffraction began as early as the 1930s (in particular, by Rigamonti, in 1936), but the interest of the crystallographic community in such a technique soon faded, mostly because electron diffraction intensities are not routinely transferable into kinematical |F|2. In spite of this limitation, the technique has been used for investigating the structure of many inorganic, organic, and metallo-organic crystals, biological structures, and various minerals, especially layer silicates.

Abstract:
The design of novel medicines, insecticides, perfumes, flavourings, or polymeric materials relies crucially on organic chemists. ‘The synthesis and analysis of organic compounds’ outlines how the synthesis of an organic compound is devised to ensure that each atom is in the correct position within the molecule. It explains retrosynthesis and how reactions are carried out and monitored using chromatography and infrared spectroscopy. Once a reaction has been carried out, it is necessary to isolate and purify the reaction product. The structure of the end product needs to be analysed by elemental analysis, mass spectrometry, X-ray crystallography, or nuclear magnetic resonance spectroscopy. Another important part of organic chemistry is understanding how reactions take place.
