Using Pyridinyl-Substituted Diaminotriazines to Bind Pd(II) and Create Metallotectons for Engineering Hydrogen-Bonded Crystals
Bibliographic record
Abstract
The pyridinyl groups of pyridinyl-substituted diaminotriazines 3a,b and 4a,b can bind metals, and the diaminotriazinyl (DAT) groups serve independently to ensure that the resulting complexes can participate in intercomplex hydrogen bonding according to characteristic motifs. As planned, ligands 3a,b and 4a,b form trans square-planar 2:1 complexes with PdCl(2), and further association of the complexes is directed in part by hydrogen bonding of the DAT groups. Similarly, ligands 3a,b and 4a,b form cationic square-planar 4:1 complexes with Pd(BF(4))(2), Pd(PF(6))(2), and Pd(NO(3))(2), and the complexes again typically associate by hydrogen bonding of the peripheral DAT groups. The observed complexes have predictable constitutions and shared structural features that result logically from their characteristic topologies and the ability of DAT groups to engage in hydrogen bonding. These results illustrate the potential of a hybrid inorganic/organic strategy for constructing materials in which coordinative bonds to metals are used in conjunction with other interactions, both to build the molecular components and to control their organization.

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.
