Abstract
Abstract The crystal structure of tedhadleyite, ideally Hg 2+ Hg 10 1+ O 4 l 2 (Cl,Br) 2 ,triclinic, AĪ, a 7.0147(5), b 11.8508(7), c 12.5985(8) Å, α 115.583(5), β 82.575(2), γ 100.619(2)º, V 927.0(2) Å 3 , Z = 2,was solved by direct methods and refined to an R 1 index of 4.5% for 2677 unique reflections. There are six symmetrically distinct Hg sites in tedhadleyite: Hg (1) is occupied by Hg 2+ and Hg(2–6) are occupied by Hg + that forms three [Hg–Hg] 2+ dimers with Hg–Hg separations between 2.527 and 2.556 Å. These [Hg–Hg] 2+ dimers have strong covalent bonds to O atoms,forming pseudo-linear O–Hg–Hg–O arrangements,and weak bonds to halogen and O atoms at high angles to the dimer axis. The [O–Hg–Hg-O] groups share anions to form four-membered square rings of composition [Hg 8 O 4 ] that link along [100] via [O–Hg–Hg-O] groups and along [001] via [O–Hg–O] groups, forming rectangular rings of composition [Hg 14 O 8 ]. The rings form a corrugated layer that interweaves with a symmetrically related layer whereby the [O–Hg(6)–Hg(6)–O] linking groups of one layer pass through the centres of the square [Hg 8 O 4 ] rings of the other layer to form [Hg 11 O 4 ] complex slabs parallel to (010) that link through Hg-I and Hg-Br,Cl bonds.

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
