For the datasets used to determine and refine representative structures of each compound, either from 200 kV EBEC data or 300 kV data from the TVIPS camera, data was reduced and scaled as detailed above (though a high-resolution cutoff of 0.9 Angstroms for integration was applied for 300 kV data from Co(II)-porphyrin), and multiple datasets were merged for each crystal as needed to improve completeness. Phases were retrieved by direct methods using either SHELXT or SHELXD, and refined in SHELXLE with addition of riding H-atoms and anisotropic treatment of ADPs, applying geometry restraints where needed for refinement to proceed stably. The R1, wR2, and goodness of fit statistics after this treatment were recorded, a CIF file saved, validated by the service checkCIF and deposited in the Cambridge Crystallographic Data Centre (CCDC) database.
