Influence of Ligand Substitution Pattern on Structure in Cobalt(II) Complexes of Bulky <i>N</i>,<i>N′</i>‐Diarylformamidinate <i>N</i>‐Oxides
Bibliographic record
Abstract
Abstract Cobalt(II) complexes of bulky N , N′ ‐diarylformamidinate N ‐oxide ligands were synthesized and structurally characterized. The cobalt(II) bis(chelates) are square‐planar (low spin) in the solid state, according to XRD and magnetic measurements ( μ eff = 1.8 to 2.1 μ B ), but show square‐planar (low spin) to tetrahedral (high spin: μ eff = 3.5 to 4.7 μ B ) isomerization in solutions of noncoordinating solvents, as demonstrated by different spectroscopic techniques. The isomerization equilibrium is highly sensitive to the substitution pattern on the ligand due to a combination of steric and electronic influences.

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.
