Method for the computational comparison of crystal structures. [link]Paper  doi  abstract   bibtex   
A new method for assessing the similarity of crystal structures is described. A similarity measure is important in classification and clustering problems in which the crystal structures are the source of information. Classification is particularly important for the understanding of properties of crystals, while clust ering can be used as a data reduction step in polymorph prediction. The method described uses a radial distribution function that combines atomic coordinates with pa rtial atomic charges. The descriptor is validated using experimental data from a classification study of clathrate structures of cephalosporins and data from a polym orph prediction run. In both cases, excellent results were obtained.
