A dipalladium complex with a single hydroxo bridge and its methylpalladium precursor
Bibliographic record
Abstract
The reaction of [PdClMe(Me2NCH2CH2NMe2)] with bis(2-pyridylmethyl)amine, bpma, gave the methylpalladium complex [PdMe(bpma)]Cl, which could be converted to the triflate or tetrafluoroborate salt by reaction with AgOTf or AgBF4. Further reaction of [PdMe(bpma)]OTf with B(C6F5)3 or HOTf gave the complex [Pd2(micro-OH)(bpma)2](OTf)3, which contains a bridging hydroxo ligand and no other bridging ligand, and whose structure contains an unexpectedly large Pd-O-Pd angle of 141.2(3) degrees. This complex acts as a model for complexes proposed to be formed during hydrolysis in aqueous solution of biologically active compounds such as cisplatin.

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.
