Crystallographic and structural analysis of iron heterometallic hexa- and heptanuclear complexes
Bibliographic record
Abstract
This review covers over 100 heterohexa- and almost 60 heteroheptameric iron clusters. There are six categories of the heterohexameric complexes: Fe5M, Fe4M2, Fe3M3, Fe2M4, FeM5 and Fe4MM′, and eight categories of the heteroheptameric complexes: Fe6M, Fe5M2, Fe4M3, Fe3M4, Fe2M5, FeM6, FexMyM′z and FeRu4CuAu. The heterometals include the non-transition and transition metals. The shortest Fe-M (non-transition) and Fe-M (transition) in the heterohexa- series are 2.444(3) Å for Fe-Ge and 2.404(20) Å for Fe-Cu, and in the heterohepta- series are 2.316(2) Å for Fe-Ge and 2.438(3) Å for Fe-Au. Correlations between structural parameters, heterometals and ligand donor atoms are developed and an overall summary of the metal-metal distances is given.

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.
