Linear End‐On Coordination Modes of CO<sub>2</sub>
Bibliographic record
Abstract
Abstract The second case of linear end‐on and evidence for an unprecedented bridging end‐on coordination mode of CO 2 have been discovered for vanadium aryloxide complexes of the tetradentate ligand system (ONNO) 2− (ONNO=2,4‐Me 2 ‐2‐(OH) C 6 H 2 CH 2 ] 2 N(CH 2 ) 2 NMe 2 ). The reaction of divalent (ONNO)V II (TMEDA) with CO 2 and under the appropriate reaction conditions affords the trivalent (ONNO)V III (OH)(η 1 ‐CO 2 ) resulting from an intermediate CO 2 deoxygenation pathway followed by H‐atom abstraction from the aromatic solvent, and CO 2 fixation. In contrast, the reduction of trivalent (ONNO)V III Cl(THF) with K, followed by exposure to CO 2 in ethereal solvent, afforded the dinuclear [(ONNO)V II ] 2 (μ , η 1 ‐CO 2 ).

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.
