Crystal-Structure Studies by Neutron and X-Ray Diffraction

[摘要] The theme of this thesis is the study of hydrogen bonding, mainly in acid salts, by neutron and X-ray diffraction. In Part I some aspects of the theory and practice of neutron diffraction and its application to the study of crystal structure are discussed and comparisons made with X-ray diffraction. Part II contains a short review of hydrogen bonding. The crystal-structure analyses by neutron diffraction of the acid salts potassium tetroxalate and potassium hydrogen malonate and of the Tutton salt ammonium nickel sulphate hexahydrate are described in Part III. The structure of each compound is discussed. In Part IV the X-ray crystal-structure analysis of the acid salt 1-methyl-2-quinolonium dihydrogen arsenate is described and its structure discussed. Also described is the structure analysis of a material which was thought to be potassium deuterium di-aspirinate, but which was recently found not to be deuterated. A reprint of a published paper (Currie, Curry and Speakman, 1967) on the crystal-structure analysis by neutron diffraction of ammonium tetroxalate, which is isomorphous with potassium tetroxalate, is included as Appendix I, and a note on the setting-up of crystals on a four-circle neutron diffractometer as Appendix II.
