Unprecedented Octanuclear Dy<sup>III</sup> Cluster Exhibiting Single-Molecule Magnet Behavior
Bibliographic record
Abstract
An unprecedented Dy 8 cluster, [Dy 8 (μ 4 -O)(μ 3 -OH) 8 (vht) 4 (NO 3 ) 2 (H 2 O) 8 ](NO 3 ) 4, composed of two fused and distorted [Dy 4 (μ 3 -OH) 4 ] 8+ cubane units is reported. The bridging of the two cubanes occurs through a planar μ 4 -O (oxide) moiety, and leads to the largest reported distortion of the Dy-O-Dy angles within a [Dy 4 (OH) 4 ] cubane core. In turn, this leads to clear zero-field slow relaxation of the magnetization, characteristic of single-molecule magnets (SMMs). Further magnetic analyses suggest that the relaxation may be largely dictated by quantum tunneling of the magnetization and Raman processes.

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.
