Self-Assembly Using Dynamic Coordination Chemistry and Hydrogen\nBonding: Mercury(II) Macrocycles, Polymers and Sheets
Bibliographic record
Abstract
The self-assembly of extended metal-containing arrays is described based on dynamic coordination chemistry at\nmercury(II) with bis(amidopyridyl) ligands to form macrocycles, polymers, or sheets which can be further organized\nby hydrogen bonding between amide substituents. The ligands 1,2-C<sub>6</sub>H<sub>4</sub>{NHC(O)-4-C<sub>5</sub>H<sub>4</sub>N}<sub>2</sub>, <b>1</b>, 1,2-C<sub>6</sub>H<sub>4</sub>{C(O)NHCH<sub>2</sub>-4-C<sub>5</sub>H<sub>4</sub>N}<sub>2</sub>, <b>2</b>, and 1,2-C<sub>6</sub>H<sub>4</sub>{CH<sub>2</sub>C(O)NHCH<sub>2</sub>-4-C<sub>5</sub>H<sub>4</sub>N}<sub>2</sub>, <b>3</b> can adopt polar conformations and so can confer\nhelicity in their complexes. Several macrocycles of formula [(HgX<sub>2</sub>)<sub>2</sub>(μ-LL)<sub>2</sub>] (LL = <b>1</b>, <b>2</b>), with tetrahedral mercury(II) centers, were prepared in which individual molecules are further self-assembled via hydrogen bonding in the\nsolid state to form one- or two-dimensional polymers or sheets. In one case, a one-dimensional polymer [{(HgX<sub>2</sub>)(μ-<b>3</b>)}<i><sub>n</sub></i>] was formed. It is shown that the mercury(II) centers can be six-coordinate in forming the sheet structure\n[{(HgX<sub>2</sub>)(μ-<b>2</b>)<sub>2</sub>}<i><sub>n</sub></i>], in which there are particularly large pores.

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.
