A repository for small-molecule organic and metal-organic crystal structures. Contains the results of over half-a-million x-ray and neutron diffraction analyses, and includes unique directly deposited data.
ChemSpider is a chemistry search engine. It has been built with the intention of aggregating and indexing chemical structures and their associated information into a single searchable repository and make it available to everybody, at no charge.
Searchable database of material properties includes data sheets of thermoplastic and thermoset polymers such as ABS, nylon, polycarbonate, polyester, polyethylene and polypropylene; metals such as aluminum, cobalt, copper, lead, magnesium, nickel, steel, superalloys, titanium and zinc alloys; ceramics; plus semiconductors, fibers, and other engineering materials.
Data available include Thermochemical Data, Reaction thermochemistry data, IR Spectra, UV-VIS Spectra, Mass Spectra, Electronic and vibrational spectra, Constants of diatomic molecules (spectroscopic data), Ion energetics data, Thermophysical property data.
