Acta Crystallographica Section C: Crystal Structure Communications publishes crystal structures determined by diffraction methods. It specialises in the rapid dissemination and archiving (for Internet access) of high-quality studies of new, novel and challenging crystal and molecular structures of interest to the fields of chemistry, biochemistry, mineralogy, pharmacology, physics and materials science. To achieve this objective, it operates a unique submissions policy, requiring authors to submit papers in the format of a Crystallographic Information File (CIF).
Before you prepare your paper first read Notes for Authors which give an overview of how to proceed. You will be required to submit your paper in CIF format and the CIF should be checked using checkCIF (see Your CIF below) before submission.
