Crystallography Open Database - an open-access collection of crystal structures.
The Crystallography Open Database (COD) provides open-access to over 80,000 inorganic, metal-organic, and small organic molecule structural data entries. This growing database ensures broad coverage of crystallographic research publications.
Area of Science:
- Crystallography
- Materials Science
- Chemistry
Background:
- The need for a centralized repository of structural data is crucial for scientific advancement.
- Existing databases may have limitations in scope or accessibility.
Purpose of the Study:
- To describe the Crystallography Open Database (COD) and its open-access model.
- To highlight the current scope and growth of the COD.
Main Methods:
- Data compilation from various sources, including International Union of Crystallography publications.
- Adoption of the crystallographic information file (CIF) format.
- Implementation of an open-access model.
Main Results:
- The COD currently houses approximately 80,000 entries.
- The database demonstrates nearly full coverage of International Union of Crystallography publications.
- The COD is continuously expanding in both size and data quality.
Conclusions:
- The COD serves as a valuable, accessible resource for crystallographic structural data.
- The open-access nature of the COD promotes wider scientific collaboration and data utilization.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
