Since February 1999, there has been an agreement between Cambridge Crystallographic Data Centre (CCDC) and FIZ Karlsruhe that all organic and organometallic compounds should be deposited at CCDC and all inorganic and intermetallic compounds at FIZ Karlsruhe. Crystal structures submitted to FIZ Karlsruhe should contain neither C-C nor C-H bonds. Please send inorganic structure data to crysdata(at)fiz-karlsruhe(dot)de and organic structure data to CCDC, deposit(at)ccdc.cam.ac(dot)uk.
