There are now programs that automate building, optimizing, and analyzing DFT structures (ground state and transition states). For example, our Mason program automates building and optimizing transition states using a ligand library. The most notable general program to obtain transition states through automated functionalization of specific ligand sites is the AARON toolkit. Wheeler has very recently developed a powerful suite of tools for structure building, transition-state optimization, and job control, which is called QChASM. Pidko and Sinha's ChemSpaX program can also perform ligand derivatization for organometallic complexes. There are also a few other programs that can also rapidly build transitionmetal complexes, most notably Kulik's molSimplify. Other notable programs include Jensen's DENOPTIM that provides the general design of compounds, including organometallic structures. While there are now programs that can automate catalyst building there remains a lack of extensive ligand libraries. Therefore, our goal was to develop a ligand library based on experimentally reported ligands that when used for catalyst design harmonize the handoff from computation to experiment. Additionally, an experimentally based ligand library would enable the comparison of hypothetical chemical space with currently reported synthetic chemical space.
