Abstract
[163167-60-0] C30H22Cl2Zr (MW 544.63) InChI = 1S/2C15H11.2ClH.Zr/c2*1-2-6-12(7-3-1)15-10-13-8-4-5-9-14(13)11-15;;;/h2*1-11H;2*1H;/q;;;;+2/p-2 InChIKey = JEKOISATHYKFFC-UHFFFAOYSA-L (efficient catalyst for polymerizations) Alternate Name: dichlorobis[(1,2,3,3a,7a-η)-2-phenyl-1H-inden-1-yl]zirconium. Form Supplied in: according to literature procedure.1 Solubility: soluble in toluene.2 Analysis of Reagent Purity: 1H NMR.1 Preparative Methods: can be prepared by reaction of 2-phenylindenyllithium with ZrCl4.1 Handling, Storage, and Precautions: store in a cool, dry place in a tightly sealed container. Handle and store under an inert atmosphere of nitrogen or argon. Generally used within an inert atmosphere dry box, contact with oxygen is strictly avoided. May cause mild to severe irritation of the eyes, skin, nose, mucous membrane, or respiratory tract. Avoid ingestion, inhalation, or direct contact with skin or clothing. The toxicological effects of this reagent have not been thoroughly tested, unknown hazards may be present. Disposal: dispose off according to local, state, provincial, and federal guidelines relating to zirconium compounds and organometallic reagents. Small spills can be mixed with vermiculite, sodium carbonate, or other suitable non-combustible adsorbent and swept up. The compound is most likely incompatible with oxidizing agents and active metals.

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.
