The Cambridge Structural Database (CSD) contains structural information on over 330,000 carbon containing molecules (<1000 atoms) and over 366,000 structures, including organics, compounds of main group elements, organometallics and metal complexes. There is a small overlap between the CSD and the Inorganic Crystal Structure Database, in the area of molecular inorganics.
The database of the Structure Commission of the International Zeolite Association provides structural information on all zeolite structure types. This includes crystallographic data and drawings drawings for all zeolite framework types, simulated powder patterns for representative materials and relevant references
DIPPR is a web-based compilation of experimental physical and thermodynamic property data for over 1,800 pure chemicals. (Contact us for the password. Access only granted to Caltech faculty, students and staff. )
Searchable database of ~120,000 inorganic structures, including elements, compounds, minerals, and intermetallics. Display options include Unit Cell Visualization and Powder Patterns.
Includes articles on chemical substances—including their properties, manufacturing, and uses. It also focuses on industrial processes and unit operations in chemical engineering, as well as covering fundamentals and scientific subjects related to the field. Additionally, environmental and health issues concerning chemical technology are also addressed.
1940+ mathematical reviews and summaries of journal articles and books; more info. For earlier material (1868-1930) see also Jahrbuch Project (in German and English)
