Abstract
Abstract Hf 5 Sb 9 was the first and thus far only example of an inorganic material that contains a pure T net, i.e. a planar layer of three‐bonded Sb atoms. It crystallizes in a super structure of the ZrSiS type, wherein the originally square layers are diluted and deformed to form said T net. Each Sb atom of this net, labeled Sb3, is connected to three symmetry equivalent Sb atoms at distances of about 3Å, reminiscent of molecular T examples such as BrF 3 . According to electronic structure calculations, these three Sb3–Sb3 interactions correspond to medium strong bonds. Hf 5 Sb 9 is a high‐temperature antimonide that decomposes slowly under formation of HfSb 2 at intermediate temperatures such as 750 °C, while it can be stored literally for years at room temperature. Like all other studied binary hafnium antimonides, Hf 5 Sb 9 is metallic with a small Seebeck coefficient.

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
