Figure shows the importance of chloride, pyridine and carbonyl coordination in TMC chemistry. Here we leverage the graph information in the SMILES to extract these coordination patterns that also includes information on aromaticity of the coordinating atoms neighbors. Such insights are crucial when making design choices in accelerated TMC discovery as they can be used to adjust the search scope or to design custom synthetic accessibility (SA) scores for use in generative models. An example would be in TMC catalyst discovery where ligand coordination environments can be used to either set up a starting geometry for TMCs to search for, or as a look-up table for potential coordination environments in new ligand candidates.
