A comparison of five X-ray structures of transition-metal-bound hydride complexes, refined using Hirshfeld Atom Refinement (HAR), shows that using aspherical atomic scattering factors results in systematic elongation of metal-hydrogen bonds. This leads to excellent agreement between X-ray and neutron-derived bond lengths in cases of highest-quality data.
A comparison of five X-ray structures of transition-metal-bound hydride complexes, successfully refined using Hirshfeld Atom Refinement (HAR) against low resolution X-ray diffraction data (including the positions and ADPs of all hydrogen atoms), with neutron structures shows that using aspherical atomic scattering factors instead of spherical ones results in systematic elongation of metal-hydrogen bonds, which in the case of the highest-quality data leads to excellent agreement of the X-ray and the neutron-derived bond lengths.
