Abstract

fetched live from OpenAlex

The title palladacycle, [Pd(C9H12N)Cl(C7H10N2)] or [Pd(DMBA)Cl(DMP)] [DMBA is 2-(dimethyl­amino)benzyl, N(CH3)2–CH2C6H4, and DMP is 4-(dimethyl­amino)pyridine, 4-N(CH3)2C5H4N], crystallizes with three crystallographically independent but conformationally almost identical mol­ecules (A, B and C) in the asymmetric unit. In all three mol­ecules, the Pd atoms are coordinated by slightly distorted square-planar arrays of two N (pyridine and amine), benzyl C and Cl atoms. The pyridine and amine N atoms are positioned trans to one another. The dihedral angles between benzene and pyridine rings are 7.47 (17), 7.34 (16) and 10.83 (15)° in mol­ecules A, B and C, respectively. In the crystal structure, weak intra- and inter­molecular C—H⋯N and C—H⋯Cl and C—H⋯π inter­actions stabilize the structure.

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.
