Abstract
The title compound, C 28 H 24 N 6 S 4 , synthesized by the reaction of 2,3,5,6-tetrakis(bromomethyl)pyrazine with 2-mercaptopyridine, crystallizes with one half-molecule in the asymmetric unit. The whole molecule is generated by inversion symmetry, the centre of the pyrazine ring being located about an inversion centre. The pyridine rings of the unique (pyridin-2-ylsulfanyl)methyl substituents are inclined to the pyrazine ring by 38.7 (3) and 75.6 (2)°, and by 66.0 (3)° to one another. In the crystal, molecules are linked via C—H...π interactions, forming chains along the b -axis direction. The chains are linked by offset π–π interactions [intercentroid distance = 3.682 (3) Å], forming layers lying parallel to the bc plane.

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
