Abstract

fetched live from OpenAlex

In the asymmetric unit of the title compound, C(13)H(11)N(3)OS·0.5H(2)O, there are two independent mol-ecules of 4-benzyl-3-(2-fur-yl)-1H-1,2,4-triazole-5(4H)-thione and a water mol-ecule of hydration. The conformation of the two organic mol-ecules is slightly different, the dihedral angles formed by the furyl and triazole rings being 5.63 (15) and 17.66 (13)°. The water mol-ecule of hydration links three adjacent triazole mol-ecules to form a cluster via inter-molecular O-H⋯S, N-H⋯S and N-H⋯O hydrogen bonds, generating a 10-membered ring of graph set R(3) (3)(10). The crystal structure is further stabilized by intra- and inter-molecular C-H⋯S, C-H⋯O and C-H⋯N hydrogen bonds and by π-π stacking inter-actions involving the furyl and triazole rings of centrosymmetrically related mol-ecules, with a centroid-centroid separation of 3.470 (2) Å.

Full frame distilled prediction

Teacher imitation

Not 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.
