Abstract
(NiCl2) [7718-54-9] Cl2Ni (MW 129.59) InChI = 1S/2ClH.Ni/h2*1H;/q;;+2/p-2 InChIKey = QMMRZOWCJAIUJA-UHFFFAOYSA-L (NiCl2ċ6H2O) [7791-20-0] Cl2H12NiO6 (MW 237.71) InChI = 1S/2ClH.Ni.6H2O/h2*1H;;6*1H2/q;;+2;;;;;;/p-2 InChIKey = LAIZPRYFQUWUBN-UHFFFAOYSA-L (mild Lewis acid;2-5 catalyst for coupling reactions,1a,7-12 and in combination with complex hydrides as a selective reducing agent16, 33, 36-38) Physical Data: mp 1001 °C; d 3.550 g cm−3. Solubility: sol H2O, alcohol; insol most organic solvents. Form Supplied in: yellow solid when anhydrous, green solid for the hydrate; widely available. Drying: for anhydrous nickel chloride, standard procedure for drying metal chlorides can be used by refluxing with Thionyl Chloride followed by removal of excess SOCl2.45 Handling, Storage, and Precautions: nickel(II) is reputed to be toxic and a cancer suspect agent. Use in a fume hood.
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.
