Ti<sub>5</sub>Si<sub>1.3</sub>Sb<sub>1.7</sub> The first titanium silicide antimonide, forming a crystal structure not found in either binary system
Bibliographic record
Abstract
Ti 5 Si x Sb 3 x can be prepared by melting mixtures of Ti, Si, and TiSb 2 . The ternary phase with x = 1.32(5) crystallizes in the W 5 Si 3 type (space group I4/mcm, Z = 8, for x = 1.32(5): a = 1034.6(2), c = 515.2(1) pm), while Ti 5 Sb 3 and Ti 5 Si 3 adopt the Yb 5 Sb 3 type and the Mn 5 Si 3 type, respectively. The Si and Sb atoms share two sites in Ti 5 Si 1.32(5) Sb 1.68 : 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.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
