(η<sup>5</sup>-Cyclopentadienyl)[(1,2,3,4,4a,10a-η)-1-methylthianthrene]iron(II) hexafluoridophosphate acetone 0.33-solvate
Bibliographic record
Abstract
The title complex salt, [Fe(C(5)H(5))(C(13)H(10)S(2))]PF(6).0.33C(3)H(6)O, obtained from an acetone-diethyl ether-dichloromethane mixture at 280 (2) K, has three cationic molecules (A-C), three hexafluoridophosphate counter-anions and one acetone solvent molecule in the asymmetric unit. Two of the three cations contain FeCp (Cp is cyclopentadienyl) inside the fold of the heterocycle. The dihedral angles between the planes of the external (complexed and uncomplexed) benzene rings in the thianthrene molecule are 146.5 (2) degrees for FeCp-out-of-fold molecule A, and 139.0 (3) and 142.5 (2) degrees for the two FeCp-in-fold molecules B and C, respectively. The complexed Cp and benzene rings in each molecule are almost parallel, with a dihedral angle between the planes of 0.2 (5) degrees for molecule A, 2.8 (5) degrees for B, and 2.19 (4) and 6.86 (6) degrees for the disordered Cp ring in C.

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.
