The remaining functionals with low fractions of exchange, all GGAs (i.e., BLYP ) and all other meta-GGAs (i.e., TPSS 113 and SCAN 166 ) except the Minnesota meta-GGAs (i.e., M06-L 160 and MN15-L 167 ) stabilize low-spin (LS) states with the average of their DGH-L distributions ranging between 10.1 and 15.7 kcal/mol, predicting SCO behavior for only a few (≤ 7) complexes (Figure and Supporting Information Figures and Table ). There is nothing obviously different about the few complexes predicted to be SCOs by GGAs or meta-GGAs, as most are representative of the full set (i.e., are Fe(II)/N), except for one Fe(II)/S complex (refcode: WIHQIQ 156 ), and all are experimentally verified SCO complexes with either single-step (five cases) or two-step (two cases) SCO behavior (Supporting Information Table and Figure ).
