Stability of [2]Pseudorotaxanes Templated Through Second-Sphere Coordination
Bibliographic record
Abstract
A series of nine trans-dichlorobis(pyridine)palladium(II) complexes were prepared (2a-i), containing different 4-substituted pyridine co-ligands. The association constants between these Pd-complexes and 1 were measured, and their values plotted against corresponding sigma(p) degrees values. Measurement of the hydrogen bond acceptor capability of the chloride co-ligands revealed the presence of a linear free energy relationship between the electronic induction of a given 4-substituted pyridine co-ligand and the subsequent complexation strength in [2]pseudorotaxane formation. These trends also extended to trans-dibromobis(pyridine)palladium(II) (3a-e) and trans- dichlorobis(pyridine)platinum(II) complexes (5a-e) when plotted against sigma(p) degrees values. In addition, solid-state structures of three [2]pseudorotaxanes (1.2h, 1.2i, and 1.5e) were determined by single crystal X-ray diffraction further confirming the viability of this template in forming interpenetrated molecular architectures.

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.
