Synthesis and Characterization of Co Complexes Coordinated by a Tetraanionic Bis(amidateanilido) Ligand
Bibliographic record
Abstract
High Resolution Image Download MS PowerPoint Slide The synthesis and characterization of a square planar Co II complex coordinated by the tetraanionic bis(amidateanilido) L 4– ligand, 1 2–, and its corresponding one-electron oxidized forms 2 –, 3, and 4 + are discussed herein. 1 2– undergoes aerobic oxidation to form 2 –, a square planar S = 1 Co III complex. This aerobic reactivity is attributed to a remarkably negative Co II /Co III potential, as observed in its cyclic voltammogram, which is among the most negative Co II /Co III couples reported. This supports the conclusion that the L 4– ligation is strongly stabilizing to the oxidized Co III center. The cyclic voltammogram of 2 – also reveals that further oxidations are possible at mild potentials. Indeed, the stoichiometric addition of a suitable chemical oxidant yields a ligand-oxidized S = 1/2 Co III complex, 3, while the addition of a further equivalent of the oxidant putatively yields 4 + . The formation of the ligand oxidized species 3 suggests that bis(amidateanilido) ligation can further behave as a redox-active ligand upon additional oxidation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
