Abstract

1-Aminocycloheptanecarboxylic acid hydrobromide monohydrate crystallizes in space group P212121 with cell dimensions a=25·69, b=6·85 and c=6·61Å. The structure was solved in the hk0 and h0l projections, and refined with the three-dimensional data to an R factor of 9·86%. The cycloheptane ring is disordered, which leads to 'predominant' and 'alternative' conformations. Both of these conformations correspond to a skew-chair form. The structure is stabilized by a three-dimensional network of hydrogen bonds.
