While we do not expect to discover any new stable structures, it is an interesting phase space to explore with a generative model owing to its complexity and importance in solid-state chemistry. The Materials Project database lists 44 TiO₂ crystal structures, involving several extensively studied polymorphs. It includes the commonly found rutile, which features an octahedral geometry around each titanium ion in a tetragonal symmetry. Anatase, another well-known tetragonal polymorph close in energy to rutile, but with more distorted octahedra. TiO₂ can also exist in other forms, such as brookite and TiO₂-B, and these polymorphs can be accessed depending on processing conditions such as temperature, pressure, and chemical environment. This structural flexibility makes TiO₂ highly versatile for applications. Using Chemeleon, 549 TiO₂ potential polymorphs, distinct from the known structures were sampled with compositions ranging in multiplicity from 1 to 13. Following preliminary geometry optimization using MACE-MP, 539 of these structures successfully converged. To compare the generated polymorphs with the known ones, we constructed a t-SNE plot based on their structural embeddings derived from CrystalNN fingerprints, as shown in Figure . The names of entries for all known materials are displayed in Supplementary Figure . It is worth highlighting that the generated polymorphs, depicted as light grey points on the plot, not only encompass most known polymorphs but also occupy previously unexplored regions of the structural space.
