Bibliographic record
Abstract
Ti5SixSb3x can be prepared by melting mixtures of Ti, Si, and TiSb2. The ternary phase with x = 1.32(5) crystallizes in the W5Si3 type (space group I4/mcm, Z = 8, for x = 1.32(5): a = 1034.6(2), c = 515.2(1) pm), while Ti5Sb3 and Ti5Si3 adopt the Yb5Sb3 type and the Mn5Si3 type, respectively. The Si and Sb atoms share two sites in Ti5Si1.32(5)Sb1.68: one site is located within a linear chain with short interatomic bonds, which is almost exclusively occupied by Si (i.e., 92(1)% Si and 8% Sb), whereas the second site, being occupied by 80(2)% Sb and 20% Si, shows no significant interactions between the main group elements. Band structure calculations reveal the new silicide antimonide being metallic as a consequence of partly filled Ti d states. The structure is mainly stabilized by bonding TiSb, TiSi, and SiSi interactions.Key words: titanium, silicide, antimonide, crystal structure, electronic structure, structure and bonding.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
