|Title:||Diffraction Studies of Hydrazinium Compounds|
|Authors:||Anderson, Rousselange Martin|
|Abstract:||<p>A neutron diffractometer has been designed and used to investigate the mechanism of the supposed ferroelectric switching in Li (N₂H₅)SO₄. This was done by studying the effect of the anomalous scattering of neutrons from ⁶Li on the structure factors of Bijvoet pairs. The absence of any observable change confirms that Li(N₂H₅)SO₄ is not ferroelectric.</p> <p>The crystal structures of Li (N₂H₅) BeF₄, Li (NH₃OH)SO₄ and (N₂H₆)BeF4 have been determined, and an accurate redetermination of the crystal structure of Li(N₂H₅)SO₄ has been made: all by X-ray diffraction. The structure of Li(N₂H₅)BeF₄ has also been studied by neutron diffraction. In the crystal structure determinations, all hydrogen atoms were located and hydrogen bonding schemes proposed; these were verified by the method of bond-strength summations.</p>|
