Multinuclear Solid-State Magnetic Resonance Study of In<sup>+</sup> and Ag<sup>+</sup> in Neutral Weakly Coordinating Environments
Bibliographic record
Abstract
A comprehensive multinuclear solid-state magnetic resonance study of In(I)- and Ag(I)bis(imino)pyridine systems is presented. Solid-state 115 In and 109 Ag NMR experiments are utilized to probe the metal cation centers, which are very weakly coordinated to the bis(imino)pyridine ligands. Along with solid-state 15 N NMR data, it is shown that the metal cations interact with the N atoms within the “pocket” of the ligands. Reasonable agreement between the measured and calculated 115 In NMR (electric field gradient and chemical shift) tensors is obtained. The relationship between the electric field gradient tensor and the arrangement of the metal center relative to the encumbered ligand is explored. The insights obtained aid in understanding the structure and bonding in these kinetically stable complexes of unstable metal ions and may assist in the rational design of other encumbered ligands for capturing reactive species.

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.
