<i>a</i><i>nsa</i>-Chromocene Complexes. 2. Isocyanide Derivatives of Cr(II) and Cr(III), Their Syntheses, X-ray Crystal Structures, and Physical Properties
Bibliographic record
Abstract
A variety of 18 e ansa -chromocene isocyanide complexes were prepared via ligand substitution on the carbonyl complexes. The relative π-accepting character of the different isocyanide ligands was evaluated from the structural, spectroscopic, and electrochemical properties of the complexes. One-electron chemical oxidation of the complexes generates low-spin, 17 e ansa -chromocene isocyanide cations, the structural and spectroscopic properties of which were compared with their neutral precursors. Density functional theory (DFT) calculations were performed on model complexes in order to elucidate the nature of the bonding between the chromium and the isocyanide ligands and to explain the effects of one-electron oxidation of the complexes.

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.
