Growth and characterization of a new inorganic metal–halide crystal structure, InPb<sub>2</sub>Cl<sub>5</sub>
Bibliographic record
Abstract
A new solid-state inorganic compound, indium dilead pentachloride, InPb2Cl5, was synthesized by melting InCl and PbCl2 in a vacuum-sealed quartz ampoule. The ampoule was heated to 793 K and then slowly cooled to room temperature to induce crystallization of InPb2Cl5. InPb2Cl5 crystallizes in the monoclinic crystal system adopting a space group of type P21/c, which is isostructural with other metal halides such as RbPb2Cl5, KPb2Cl5 and TlPb2Cl5. The bulk InPb2Cl5 exhibits a metallic black/grey colour, allowing it to be separated from white/yellow PbCl2 crystals. Due to the incongruent nature of the compound, the pure bulk InPb2Cl5 was not obtained. The black/grey InPb2Cl5 crystals were characterized by powder and single-crystal X-ray diffraction. InPbCl3 was also explored, however the growth was unsuccessful.

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.
