[SMP33-04] Strong hydrogen-bond generation in dense hydrous magnesium silicate phase E observed by single-crystal neutron diffraction
Keywords:hydrogen-bond, dense hydrous magnesium silicate, neutron diffraction
We expect that such information is helpful to understand the reason of stability of phase E at the high-temperature condition. A deuterated phase E single crystal was measured by neutron time-of-flight single-crystal Laue diffraction at Spallation Neutron Source, Oak Ridge National Laboratory. From preliminary structure refinement results, we found that the covalent bond O-D was inclined and displaced from the three-fold axis. Such O-D inclination should occur due to interlayer strong hydrogen-bond generation in the phase E structure. The details of the results will be given in the presentation.
