Silver(i) and Lead(ii) Halide Compounds with 4-Methyl-1,2,4-triazole-3-thiol
Bibliographic record
Abstract
Four novel silver(i) and lead(ii) halide compounds with the 4-methyl-1,2,4-triazole-3-thiol (Hmptrz) ligand, namely [Ag2(mptrz)(µ3-X)]n (X = I (1) and Br (2)) and [Pb4(µ4-O)(mptrz)4(µ2-X)2] (X = I (3) and Cl (4)), have been synthesized and characterized. The structures exhibit different dimensionality depending on the nature of the metal ions. Compounds 1 and 2 are isomorphous and have 2D layered structures based on inorganic [Ag2X2]n infinite chains (X = I and Br), in which the mptrz– ligand displays a novel pentadentate bridging coordination mode. Compounds 3 and 4 have similar structures and are composed of a discrete tetranuclear lead(ii) cluster featuring an oxygen-centred Pb4(µ4-O) tetrahedron. Compounds 1 and 2 display solid-state photoluminescent emission with the maximum at 589 and 420 nm respectively. Compounds 3 and 4 show solid-state photoluminescent emission with the maximum at 710 and 540 nm respectively. Additionally, compounds 1–4 were characterized by IR, elemental analysis, powder X-ray diffraction and thermogravimetric analysis.

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.
