Bar plot of the donor H…O distances in the X-N and X-Ray structure water H-bond network. The mean values are 2.12 (rmsd = 0.19) Å and 1.93 (rmsd = 0.18) for neutrons and X-rays, respectively. The mean H-bonding distance for water molecules in the X-ray structure is significantly shorter than for the X-N structure.
