Retraction of articles.

This article reports the retraction of articles published in Acta Crystallographica Section E between 2007 and 2009.

After further thorough investigation (see Harrison et al., 2010 ▶), articles are retracted as a result of problems with the data sets or incorrect atom assignments. Full details of all the articles are given in Table 1 ▶.
