Abstract
Succeeding RE6Ge5−xSb11+x, the ternary rare-earth germanium antimonides RE12Ge7−xSb21 (RE=La–Pr; x=0.4–0.5) represent the next level in an emerging structural series based on assemblies of RE6 trigonal prisms delimited by a polyanionic network of Ge and Sb atoms. The new orthorhombic structure type displays a wealth of bonding motifs, including Ge2 pairs, GeSb3 trigonal planes, and hypervalently bonded GeSb kinked sheets. H. Bie and A. Mar attempt bonding analysis through a Zintl–Klemm approach, which suggests that full electron transfer from the RE atoms to the anionic substructure cannot be assumed. This is confirmed by band-structure calculations, which also reveal the importance of GeSb and SbSb bonding. For the details, turn to their Full Paper on page 1465 ff.

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; both teacher heads agree on what is shown here.
