Abstract

fetched live from OpenAlex

The preparation and structural characterization of the methyl-substituted oxobenzene-bridged bisdithiazolyl radical 3b is described. Crystals of 3b belong to the monoclinic space group C 2/ c and contain two distinct radical environments, A and B . There are eight A radicals in the unit cell, which occupy general positions and form alternating twisted π-stacks running parallel to the c -axis. The four B radicals also adopt an alternating π-stack pattern, but each molecule lies on a crystallographic 2-fold rotation axis, and the overlay of neighboring radicals is centrosymmetric. Stacks of A radicals are linked by close intermolecular S···O′ and S···N′ contacts into ribbon-like arrays that weave along the y -direction, and the B radical stacks are located in columnar cavities generated by the out-of-register alignment of the ribbons of A radicals. Variable temperature magnetic susceptibility measurements indicate a strongly antiferromagnetically coupled system, a result in accord with DFT estimated exchange energies for intrastack radical–radical interactions. Four-probe conductivity measurements indicate a conductivity σ(300 K) = 9.0 × 10 –4 S cm –1, with a thermal activation energy E act = 0.13 eV.

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.
