The Chemical Structures is a complete set of molecular structures. The last version (v2.1) contains over 550 structures of organic compounds and has been released on 2008-01-03. In addition to structural data, each file contains complementary informations, like molecular weight, boiling point, melting point or InChI code.
Each structure can be accessed through a web interface. Structure are displayed with the Jmol applet. These html pages contain also Microformat data (InChI and SMILES).
The project has been translated into 5 languages (english, dutch, french, german and spanish) and new languages can be easily added by editing a single file.
The project is actually used in german and french schools.
