Welcome to the coordination geometry table website. This table was constructed by searching and analyzing the data in the Cambridge Structural Database (CSD). This table is an update of the 1997 table published by Moore and co-workers. For details about the search and analysis, see our paper in J. Chem. Educ.
How to navigate the pages:
- You can click on each tab to look at a specific analysis of the data
- The pages interface with Tableau public. However, you do not have to download Tableau or additional software
- You can click on a particular element in the periodic table on the page to see pie charts for the element. If there is a pie chart, then you can hover your mouse over the pie chart to get more information about a particular slice. If you click on the particular slice, then data on the page will be filtered only for that particular oxidation state.
- You can download any of the charts as PDF, image files, or PPT slides. You can also share the figures via social media.
- Please review the search criteria used to construct this table before you navigate the pages
Search criteria used:
- The coordination table represents data from crystal structures of metal complexes with organic ligands and does not include data from inorganic minerals, which are in the Inorganic Crystal Structure Database (ICSD) or metalloproteins, which are in the Protein Data Bank (PDB).
- Only structures that are error-free, free of disorder, have an R factor of < 0.12, and contain a complete set of 3-d coordinates were used for our analysis.
- Ligands that form chelates and pi-complexes were excluded from the search. Nonetheless, we found that this search restriction did not exclude bidentate eta2-pi complexes and thus these complexes are included in the analysis.
- The oxidation states of the metal ions were searched using the chemical name field in the database. Thus, any errors in the CSD are retained in the search and the data analysis.
