In a recent study, MACE proposes a workflow to convert the metal center and ligand SMILES/MOL to 3D structures covering all possible stereoisomers of octahedral and square planar complexes. Stereoisomers are a special class in complexes due to the unique spatial geometry of complexes where ligands around a metal center have different spatial orientations, leading to distinctive properties. For example, cisplatin shows great effectiveness as an anticancer agent and has been clinically applied, however, its trans-isomer, transplatin is found to be clinically ineffective. The inclusion of stereoisomers can further enrich the diversity of TMCs. Similar to Architector, MACE first identifies the central metal, coordination geometry and ligand SMILES and lists all possible stereoisomers: octahedral (30) and square planar (3). After removing identical and "exotic" configurations due to non-localization, 3D atom coordinates are generated via RDKitsupported DG. Post-optimization is implemented but it currently only supports the more qualitative Universal Force Field (UFF).
