Probing the Coordination Chemistry of <i>N</i>-2-Pyridylimidoyl-2-pyridylamidine: A Versatile Ligand with Multiple Coordination Sites
Bibliographic record
Abstract
The research presented herein focuses on controlling the coordination environment of Mn, Fe, and Co in coordination complexes with the ligand N -2-pyridylimidoyl-2-pyridylamidine ( Py 2 ImAm ), which possesses both a bidentate and tridentate coordinating site. The synthesis and characterization of seven new metallic complexes are described, and these results indicate that the key factor dictating which coordination site of Py 2 ImAm the metal ion prefers is the presence (or absence) of a weak acid. More specifically, the presence of a weak acid directs the metal ion to the tridentate site of Py 2 ImAm, while neutral or basic conditions lead to coordination complexes in which the metal center is bound to the bidentate pocket.

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.
