Continuing through the reaction cycle to rebound, we observe that over the codoped SACs data set, ΔE(rebound) is predominantly favorable. The energetics nevertheless span a wide range from weakly (ca. 0 kcal/mol) to strongly (ca. -140 kcal/mol) exothermic (Supporting Information Figure ). We observe near-zero rebound energetics for cases where N atoms codoped in the first and second coordination spheres, while several specific cases of SACs formed by M(III) metals with codopants in the first and second coordination spheres are strongly exothermic (i.e., -140 kcal/mol, Supporting Information Table ). In general, the ΔE(rebound) values of codoped SACs show less metal dependence than ΔE(oxo) and ΔE(HAT). The ΔE(rebound) energetics of Mn, Fe and Ru codoped SACs show strong spin state dependency, with LS codoped SACs of these metals more near-zero energetics than that of their IS counterparts. Conversely, no strong spin state dependency is observed for Co codoped SACs. In terms of oxidation state dependence, we only observe significant dependence for Ru codoped SACS, which we attribute to the highly diverse coordination environment and geometries in this study that make it difficult to isolate any specific effect of oxidation state (Supporting Information Figure ).
