Bibliographic record
Abstract
The compound bis{μ 3 -2,5-bis[ N -(4-isopropylphenyl)- P , P -diphenylphosphorimidoyl]pyrrol-1-ido-κ 3 N : N ′: N ′′}trisilver(I) trifluoromethanesulfonate deuterated benzene pentasolvate, [Ag 3 (C 46 H 44 N 3 P 2 ) 2 ](CF 3 O 3 S)·5C 6 D 6 , (I), was synthesized from two equivalents of Na L [ L = 2,5-(4- i PrC 6 H 4 N=PPh 2 )C 4 H 2 N] and three equivalents of AgOTf (OTf = OSO 2 CF 3 ). High-quality crystals of (I) formed with five deuterated benzene solvent molecules in the asymmetric unit. Notably, the bond lengths and angles between the three silver atoms are markedly different, unlike in most other reported trisilver complexes that tend to form three equivalent metal centers. Additionally, to the best of our knowledge, this is the first report of a trisilver complex with six nitrogen donors from two bisphosphinimine ligands.

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; both teacher heads agree on what is shown here.
