We have seen examples of a specific phase of each chemical composition. Recent work demonstrated crystal structure classification given only chemical compositions . On the other hand, there exist often different phases for each composition. Although we have avoided the leak of element symbols between crystal graphs and texts, there may have been a chance for our model to have connected chemical compositions with crystal structures during the training, and would fail to retrieve the different phase of a crystal of the same composition in the validation set. This was not the case and CLICS retrieved crystal structures given different phases of e.g., TmCO 4 and Na 3 PS 4 , each with the same chemical composition, not so surprisingly as we give crystal graphs, not the chemical compositions. The detailed results and discussion are provided in the supplementary information.
