Abstract

Several ways to synthesize solvated and desolvated calcium tetrahydroaluminate by wet-chemical and mechanochemical methods are presented. The result show that the diethyl ether (DEE) and tetrahydrofuran (THF) adducts of calcium tetrahydroaluminate can be prepared by ball miling under inert conditions or by mechanically assisted wet-chemical synthesis.

4. Double-bridge bonding of aluminum and hydrogen in the crystal structure of [gamma]-Al[H.sub.3]

Author

Yartys, Volodymyr A., Denys, Roman V., Maehlen, Jan Petter, Frommen, Christoph, Fichtner, Maximilian, Bulychev, Boris M., and Emerich, Hermann

Abstract

Aluminum trihydride (alane) crystallizing in the [gamma]-Al[H.sub.3] polymorphic modification was combined and structurally characterized by synchrotron X-ray powder diffraction. The crystal structure of [gamma]-Al[H.sub.3] is composed of Al[H.sub.6] octahedra as the building blocks and it forms a bifurcated double-bridge bond Al-2H-Al.

5. Synthesis and Mossbauer spectroscopic studies of chemically oxidized ferrocenyl(phenyl)phosphines

Author

Durfey, Daniel A., Kirss, Rein U., Frommen, Christoph, and Feighery, William

Subjects
Iodine compounds -- Chemical properties, Charge transfer -- Research, Mossbauer spectroscopy -- Usage, Chemistry
Abstract

A combination of NMR, UV-vis and Mossbauer spectroscopy methods demonstrates that iodine reacts with ferrocenyl(phenyl)phosphines to yield iodo(ferrocenyl)(phenyl)phosphonium salts. The charge-transfer complexes are observed where the phosphorous lone pair is unavailable and electron transfer is feasible.
