Since the publication date of the article, the authors have noted that there is insufficient evidence for the existence of the water dimer in compound 1. The data may represent half occupancy of the oxygen site, and not a water dimer. When reading the parts of the article relating to the water dimer the reader should keep in mind that a water dimer may not be present.
The authors also note that the positions of the two hydrogen atoms in the water molecule cannot be definitively determined. This may well be due to the high thermal parameter of the oxygen atom.
