The Cambridge Structural Database (CSD) is a centralized repository of structural data that contains TMCs, enabling quantitative analysis of crystal structures over a broad chemical space. Recent studies have leveraged experimental TMC structures in the CSD to understand spin crossover , redox behavior in bimetallic complexes , oxidation state and charge 2 assignment, and electronic properties. Previously curated subsets of TMCs from the CSD analyzed either a subset of metals (e.g. cell2mol ), complexes that are closed-shell in nature (e.g. tmQM ), or specific TMCs for spin-crossover applications. However, understanding the diversity of TMCs in terms of ligand characteristics (i.e. metal-coordinating atoms and ring substructures) and metal characteristics (i.e. metal distributions and coordination geometries) without restrictions on elemental identity would enable identification of areas for future in silico design while maintaining synthesizability.
