Abstract
Exposure of a dichloromethane solution of [OEPFeIIICl], where OEP is the dianion of octaethylporphyrin, to dioxygen results in its transformation into the μ-oxo bridged compound [(OEPFe)2O)]. The structure of [(OEPFe)2O)] is determined by X-ray diffraction analysis. It contains binuclear centrosymmetric [(OEPFe)2O]. The Fe atom is five-coordinated to four N atoms of the porphyrin ring and to one bridging O atom. The compound is characterized by an average Fe-N bond length of 2.096 Å. The Fe-O bond distance is 1.7739(12) Å, the Fe-O-Fe bond angle is 180.0° and the two porphyrin rings are parallel. Crystal data: triclinic crystal system, a = 10.915(4) Å, b = 12.951(4) Å, c = 13.403(4) Å, α = 118.06(1)°, β = 100.33(1)°, Γ = 102.43°, $$P\bar 1$$ space group, V = 1144.5(1) Å3, Z = 1.

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 it
