Abstract
[7783-49-5] ZnF2 (MW 103.39) InChI = 1S/2FH.Zn/h2*1H;/q;;+2/p-2 InChIKey = BHHYHSUAOQUXJK-UHFFFAOYSA-L (Lewis acid, fluorination agent) Physical Data: mp 872 °C; bp 1500 °C; d 4.95 g cm−3 at 25 °C. Solubility: sparingly sol in H2O (1.51 g 100 mL−1), but more sol in HCl, HNO3, and NH4OH. Also slightly sol in HF. Form Supplied in: white solid; widely available. Purification: the most frequent impurity is H2O and it can be removed by heating at 100 °C in a dry atmosphere. Handling, Storage, and Precautions: zinc fluoride is a moderate irritant of the respiratory tract, as well as for the skin and eye. Zinc fluoride should be manipulated in a well-ventilated fume hood, while avoiding dust formation. Dust mask or respirators may prevent dust inhalation. Skin and eye contact may be avoided by the appropriate use of gloves and safety goggles. Zinc fluoride must be stored in a tightly closed container and kept in a dry and well-ventilated place.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
