Uranocenium: Synthesis, Structure, and Chemical Bonding

Structure, chemical bonding, and 45Sc solid state NMR of Sc2RuSi2

The silicide Sc2RuSi2 was synthesized from the elements by arc-melting. The structure was refined on the basis of single crystal X-ray diffractometer data: Sc2CoSi2 type, * Manuscript Click here to view linked References

The U4Re7Si6 type - Trends in electronic structure and chemical bonding

The electronic structures and chemical bonding of selected ternary compounds of the family of A4T7X6 (of U4Re7Si6 –type) intermetallics have been studied by ab initio methods. The calculations for two series: Mg4Rh7P6, Sc4Co7Ge6, Ti4Co7Ge6 and uranium containing U4Re7Si6, U4Ru7Ge6, and U4Ru7As6 show common bonding characteristics pertaining to main T1-X and T2-X interaction (T = transition meta...

Synthesis, Structure and Bonding in Triorganogermyl-alanes and Triphenylgermyl-aluminates

Triphenylgermyl-lithium in diethyl ether/THF did not react with Al2Me6 to form [(Ph3Ge)AlMe3]Li(THF)n. Addition of TMEDA to this solution yielded crystalline Ph3GeLi(THF)TMEDA. The reaction of Ph3GeLi in diethyl ether/hexane solution with H3Al-NMe3 in diethyl ether/THF generated [Ph3GeAlH3]Li(THF)4 while the reaction with Me2AlCl led to Ph3GeAlMe2(OEt2) and the trigermyl-aluminate [(Ph3Ge)3AlMe...

Compton Spectroscopy and Chemical Bonding

In this article we show with the help of two examples how Compton spectroscopy may be used to study the effect of chemical bonding in materials as diverse as a molecular crystal and a high temperature superconductor. Compton spectroscopy has a long history as an investigative method in condensed matter physics and in fact the realisation that the Compton profile is sensitive to the effects of c...
