Cover illustration: Memantinium chloride, C12H22N+·Cl- is a medication used to treat dementia caused by Alzheimer's disease. This compound was re-crystrallized as the 0.1-hydrate from an ethanolic solution. The four six-membered rings of the adamantane-like core of the memantinium cation adopt typical chair conformations and are linked with the Cl- counter-anions via N-H...Cl hydrogen bonds. The disordered crystal lattice water molecules are in the voids of this arrangement and further consolidate the structure by O-H...Cl hydrogen bonds. See Lou, Hu & Gu [Acta Cryst. (2009). E65, o2191].

Research communications

Research communications are designed to help authors bring out the science behind their structure determinations. Authors are encouraged to report more than one structure in the same communication and also to include the results of investigations with other techniques. The Research communications format makes Acta E the natural home for structure determinations with interesting science to report.

Emerging Sources Citation Index

Acta E is included in the Emerging Sources Citation Index.
