Abstract

fetched live from OpenAlex

In the title compound, [Yb(C(24)H(40)BN(6))(2)]·C(7)H(8), the Yb atom is coordinated by two tris(3-tert-butyl-5-methyl-pyrazol-1-yl)hydridoborate [Tp(tBu,Me)] ligands. One ligand binds in the κ(3) mode, throuh three N atoms of the pyrazolyl rings, the other ligand coordinates through two N atoms of the pyrazolyl rings and the H atom attached to the central B via an agostic-type inter-action through the B-H group of the second Tp(tBu,Me) ligand, giving an overall distorted octa-hedral geometry. One of the tert-butyl groups is disordered over two sites, with occupancies of 0.65 and 0.35.

Full frame distilled prediction

Teacher imitation

Not 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.
