For further information see http://journals.iucr.org/services/authorrights.html Acta Crystallographica Section C: Crystal Structure Communications specializes in the rapid dissemination of high-quality studies of crystal and molecular structures of interest in fields such as chemistry, biochemistry, mineralogy, pharmacology, physics and mate- rials science. The numerical and text descriptions of each structure are submitted to the journal electronically as a Crystallographic Information File (CIF) and are checked and typeset automatically prior to peer review. The journal is well known for its high stan- dards of structural reliability and presentation. Section C publishes approximately 1000 structures per year; readers have access to an archive that includes high-quality structural data for over 10000 compounds.
