The Gmelin database is a large database of organometallic and inorganic compounds updated quarterly. It is based on the German publication the Gmelins Handbuch der anorganischen Chemie ("Gmelin's handbook on inorganic chemistry") written by Leopold Gmelin in 1887, and currently contains 1.5 million compounds and 1.3 million different reactions. The latest version contains every compound/reaction discovered between 1772 and 1995, with over 85,000 titles, keywords and abstracts, and is maintained by Elsevier MDL.
The database has over 800 different data fields on subjects such as the compounds electric, magnetic, thermal, crystal and physiological information.
It is the sister database to the Beilstein database, which deals with organic chemicals and reactions.
