DOI: 10.1021/acs.inorgchem.1c02229

Abstract: Neutron wavelength-resolved Laue diffraction experiments permit accurate refinement of the H-atom positions and anisotropic displacement parameters of [Mes3SbOH][O3SPh]. A multipole-based charge density refinement and a topological analysis of the refined electron density were also performed.… read more here.

Published in 2022 at "IUCrJ"

DOI: 10.1107/s2052252522000690

Abstract: Hirshfeld atom refinement (HAR) combined with fragmentation and atomic density transferability was tested on various systems, both polymeric and disordered. HAR was significantly faster with these adjustments, reducing computational time for larger systems with only… read more here.

Published in 2022 at "IUCrJ"

DOI: 10.1107/s2052252522006662

Abstract: Accurate crystal structures of H2O, D2O and mixed (50%H2O/50%D2O) ice VI obtained by Hirshfeld atom refinement (HAR) of high-pressure single-crystal synchrotron and laboratory X-ray diffraction data are presented. It was possible to obtain O—H bond… read more here.
