Single crystal neutron diffraction study of a novel MgCl2-hydrate under pressure to 1 GPa by using a newly designed pressure cell
The proposed single crystal neutron diffraction experiment aims to determine full structural parameters including hydrogen positions in a high pressure form of a salt hydrate. The sample under investigation is a high pressure phase of MgCl2 hydrate which was recently discovered by Komatsu and co-workers (Univ. Tokyo) using single crystal x-ray diffraction. The crystal structure without hydrogen positions was solved by x-ray diffraction, and the structure may have disordered water molecules involving "switching hydrogen-bonding networks", which is the main interest of this study. We will use a newly developed high pressure cell which overcomes many difficulties previously encountered in single crystal neutron diffraction under pressure.
