Figure 5
Averaged A—H bond lengths with sample standard deviations obtained from neutron diffraction versus those obtained from X-ray diffraction (HAR and IAM models) at restricted resolution (d = 0.8 Å) and with no restriction (d = max). Twenty-four bond classes Zn—A—H are taken from Allen & Bruno (2010BB4) and indicate the atom A bonded to the H atom, and in the case of A = C, the hybridization, and the number of atoms Z of any kind with n = 1, 2, 3 bonded to the C atom. For cocrystallized water, O—H bond lengths obtained from neutron diffraction using entries in the Cambridge Structural Database (CSD) were averaged. The numbers of observations for all bond types for each refinement method are given in the same colour code in the right-hand column. Reproduced with permission from Woińska et al. (2016BB326).
