Magneto‐Optical Correlations in a High Symmetry Dysprosium Complex Reveal an Almost “Ideal Non‐SMM” and Orange‐to‐Red Dy<sup>III</sup>‐Based Emitter
Bibliographic record
Abstract
The importance of investigating high‐symmetry systems in order to reveal properties that would otherwise be concealed in less symmetrical compounds is demonstrated. This is particularly true for discrete coordination complexes that tend to adopt low symmetries. The magnetic, optical, and theoretical investigation of [Dy{N(SiMe 3 ) 2 } 3 ], an amido complex that features an almost trigonal electrostatic environment around the Dy III ion, is reported here. While this specific coordination is ideally suited to the stabilization of high magnetic ground state for “ prolate” Yb III ‐based single‐molecule magnet (SMM), it is the opposite for oblate Dy III . Hence, [Dy{N(SiMe 3 ) 2 } 3 ] is expected to display the lowest conceivable magnetic anisotropy. This is confirmed herein by magneto‐optical and theoretical correlations. An extremely pure Kramers doublet composition is observed on a totally reversed energetic profile compared to the standard Dy III ‐SMM. This results in a paramagnetic but dynamically silent compound, even when an external dc field is applied. Additionally, this unusual energetic profile induces an exceptional optical signature, with orange (300 K) to red (4 K) emission, far from the traditional white‐to‐yellow emission expected for a Dy III ion.

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.
