Abstract
The cover picture shows stick and space-filling models of a crystal structure that contains transition metal ions [Mn(H2O)6]2+ (red) and their accompanying ClO4− anions (green) suspended in a sea of 4,7-phenanthroline "ligands" (blue). Curiously, there are no direct manganese–nitrogen bonds. This material is instead knitted together entirely by hydrogen bonds between coordinated water molecules and phenanthroline molecules. The inset figure (top right) depicts schematically the concepts of first-sphere (dark blue) and second-sphere (light blue) coordination. This second-sphere hydrogen bonding may be of particular interest as a methodology for the distribution of metal ions in the solid state, as many magnetic and electronic properties are known to be sensitive to spatial arrangements. The synthetic and structural details of this and related cobalt and nickel materials are outlined in the article by D. A. Beauchamp and S. J. Loeb on p. 5084 ff.

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; both teacher heads agree on what is shown here.
