Bibliographic record
Abstract
The new intermetallic phase ZrSn2-xSbx was prepared by arc-melting and annealing at 800 degrees C. It adopts the hexagonal CrSi2-type structure (Pearson symbol hP9, space group P6222 (or P6422), Z = 3, a = 5.51-5.53 A, c = 7.65-7.63 A) and exhibits a significant phase width (0.2 < x < 0.8). In contrast, the parent binary phases adopt different structures: ZrSn2 has the orthorhombic TiSi2-type structure, and ZrSb2 exists as two orthorhombic forms (alpha-ZrSb2, own type; "beta-ZrSb2", PbCl2-type). The structures of ZrSn2, ZrSn2-xSbx, and beta-ZrSb2 are distinguished by the stacking and distortion of nets with composition "ZrQ2" (Q = Sn, Sb). The CrSi2-type and TiSi2-type structures differ only minimally in energy, but interlayer Sb-Sb bonding is important in stabilizing the structure of beta-ZrSb2.

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; both teacher heads agree on what is shown here.
