3,5-Diphenyl-1,2,4-dithiazolium tetrabromidoferrate(III)
Bibliographic record
Abstract
The cation of the title salt, (C(14)H(10)NS(2))[FeBr(4)], contains a flat central NC(2)S(2) ring (r.m.s. deviation = 0.005 Å), with two attached phenyl rings that are almost coplanar [the dihedral angles between the mean planes are 2.4 (1) and 7.7 (1)° for the two phenyl rings]. The [FeBr(4)](-) anion makes short Br⋯S contacts [Br⋯S = 3.4819 (8), 3.6327 (9) and 3.5925 (9) Å] and also bridges by way of short contacts to ring H atoms of a second cation held parallel to the first by π-stacking, with a separation between the mean 1,2,4-dithia-zolium rings of 3.409 Å. The closest contacts are between a phenyl ring centroid of one cation and the ipso C atom of the phenyl ring of another cation, for which the distance is 3.489 Å. The discrete dimers are linked laterally by further Br⋯H short contacts, resulting in double sheets located parallel to the b axis and to the bis-ector of a and 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; a candidate call from one teacher head, not a consensus.
