Besides organic molecules, xTB methods are also used in the structure optimization of the tmQM 112 dataset containing 86,665 mononuclear transition metal complexes. For this set, no xTB based labels are published. However, it shows the robustness of these methods beyond organic chemistry. This point is further underlined by smaller databases capturing specific parts of the chemical space: organocatalysts in OSCAR, 113 or aggregate materials in ASBase. In Fig. , the size of the datasets featured in this work is compared against the size of QM9 115 as a well-cited reference.
