The synthesis, IR and 31P NMR spectra of the complexes of various N-aryltriphenylphosphinimines with some mercury dihalides as well as the corresponding phosphonium salts are reported. It is shown by an X-ray crystal structure analysis of the complex of the unsubstituted phosphinimine with HgCl2 that in the solid state these complexes form dimers via two Hg ∙∙∙ μ2- Cl ∙∙∙ Hg bridges.

Examination of the symmetric Hantzsch 1,4-dihydropyridine ester derivatives of the prototypical nifedipine molecule indicates the tendency of this class of molecule to form a common packing motif. Crystal structure analysis of 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylic diesters and analogs reveals that they form extended chains, characterized as the C(6) packing motif, via intermolecular (amine) N—H...O=C (C3,C5 carbonyl) hydrogen bonds. In addition, all the prepared derivatives also satisfy the basic structural requirements for their high binding efficiency to the receptor. The reproducible C(6) packing motif observed among these compounds has a use in the design of solid-state materials.

AbstractThe unstable trifluorom ethylisocyanide can be stabilized on the Fe3(CO)11 framework. Infrared data suggest that the isocyanide ligand occupies bridging positions in the solid state and in solution. This fact has been confirmed by the crystal structure analysis and by 13C NMR measurements.

The compounds 1,3-bis(diethylgallyl)benzene (3) and 1,4- bis(diethylgallyl)benzene (6) were prepared by reaction of the corresponding chloromercuriobenzenes with an excess of triethylgallium by applying pressure and higher temperatures. These compounds very easily undergo redistribution reactions in solution and in the solid state. Extremely air-sensitive crystals suitable for an X-ray crystal structure analysis were obtained from triethylgallium as solvent. The structural studies revealed the presence of tetra-coordinated carbon and gallium atoms in symmetric aryl-diethylgallyl bridging units. The coordination behavior of 3 and 6 in the solid state is quite different from that of the corresponding methyl-substituted compounds

First Time

The phenomenon of diastereotopic group recognition has been structurally documented for the first time. A diphenylphosphine-modified β-cyclodextrin having two diastereotopic phenyl groups in close vicinity to the inner cavity of this host was prepared. The crystal structure analysis reveals selective intramolecular complexation of one of the two diastereotopic phenyl groups.Key words: supramolecular chemistry, stereotopic group recognition, cyclodextrins, intramolecular complexation.
