Click on the Struct.Formula to draw the structure using
Jmol (Java enabled browsers)
Select up to 4 entries and click the Jmol button to compare their structures.
The Action Buttons:
Before clicking the following action buttons, select at least one entry found after a search.
Example Years search :
Example Journal :
Example Title or Comment search :
Example Elements search :(Enter the element symbols or choose from the Periodic Table).
Example Element Count or Chemical Name:
Example: C=Chemical Name
The ANX formula : Elements with a positive oxidation state are labelled by the first letters of the alphabet (A-M), elements with a negative oxidation state are labelled by the last letters (X-Z, W, V, U, T, S), while elements with oxidation state 0 are labelled by the letters N-R.
The Structure Type as defined by Prof. R. Allmann (Marburg) depends on the Space Group, Pearson Symbol and Wyckoff Sequence, all of which can otherwise be searched for seperately in ICSD. In a few cases the c/a ratio is used. Allmann Structure Types are at present only defined for cubic and tetragonal materials.
Example Structure Types :
Example Cell Size :
Example Wyckoff Sequence :
Example Wyckoff Symbol :
The pairs of atoms between which distance calculations are to be made according to the optional Distance Range and/or Co-ordination number. If only one atom name is given, all other types of bonded atom are considered. If a list of atom names is given eg Cu,Al then all from this list are considered. Example Distance Select :
The range of distances to be considered for the Distance Select atom pairs (also required).
Example Distance Range :
Example Coordination Numbers :
