Fluxional dynamics of terpyridine ligand in [Ru(bpy-d8)2(η2-tpy)]2+ complex
Bibliographic record
Abstract
Herein, we report the fluxional dynamic behaviour of terpyridineligand in [Ru(bpy-d8)(η2-tpy)]2+ 1. Reaction of Ru(bpy-d8)2Cl2·2H2O with 2,2′:6′,2′′-terpyridine in refluxing methanol afforded 1. Complex 1 has been characterized by 1H NMR spectroscopic analysis. Variable temperature 1H NMR data reveals that the pendant pyridine ring of the tpy ligand in Ru(bpy-d8)2(tpy)]2+ rotates which effects the adjacent ring protons. Moreover, protonation of 1 with trifluoroacetic acid (TFA) confirms that peripheral N on the pendant pyridyl ring of the tpy ligand affects the chemical shifts of protons on the tpy pendant pyridyl ring.

How this classification was reachedexpand
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.
