The physical and chemical properties of basic beryllium acetate, OBe 4 (CH 3 .CO 2 ) 6 , are those of a non-ionised substance having the unitary structure of a typical organic compound, each chemical molecule of which may be regarded as forming one co-ordination complex. The fact that the arrangement of the eleven associating units of which this molecule is composed possesses the geometrical attributes of a tetrahedron has led to a stereochemical conception of the constitution of the compound, which is confirmed by the results of X-ray analysis.

The crystal structure of single-layer graphene in comparison to graphite is discussed with regard to its crystallographic and chemical properties. In both of these polymorphs of carbon, the atomic volume of carbon, reduced to the closest packing of atoms, is practically the same and considerably smaller than in diamond. This indicates pentavalent carbon in graphene as well as in graphite. The observed elastic corrugations of the graphene layers which probably cause their amazing rigidity seem to be due to numerous weak chemical bonds within the layers.

AbstractWe review here work on two classes of compounds that have been promoted as potential hydrogen storage materials; alkali metal amides and borohydrides, highlighting how their crystal structure and chemical properties may be used to influence the key hydrogen absorption and desorption parameters in these materials.

The Way

The preparation and chemical properties of barium-oxocuprat (I) inclusive the results of the crystal structure determination by single crystal X-ray investigations are described. BaCu2O2 crystallizes isotypically with SrCu2O2 . (a = 5.72 and c = 10.06 Å. Spacegroup : D194h - 141/amd.) The influence of the bigger Ba2⨁-ion on the oxigenconfiguration surrounding the cations is discussed. It seems that the stretched O - Cu - O-dumbell is an invariable structural element in the oxocompounds of copper (I), which is shown by comparison of already known oxocuprates (I) . Only the way of interchainment varies evidently with stoichiometry.
