<i>rac</i>-1-Phenylethylammonium carboxymethylphosphonate(1–): hydrogen-bonded anion sheets with pendent cations
Bibliographic record
Abstract
In the title compound, C8H12N+.C2H4O5P-, the anions are linked by two O-H...O hydrogen bonds [H...O both 1.75 A, O...O = 2.5781 (15) and 2.5834 (15) A, and O-H...O = 169 and 176 degrees ] into sheets built from alternating R2(2)(8) and R6(6)(32) rings. Each cation is linked to an anion sheet by three N-H...O hydrogen bonds [H...O = 1.88-2.04 A, N...O = 2.7603 (16)-2.9334 (17) A and N-H...O = 162-166 degrees ], such that all the cations pendent from one face of the sheet are of the R configuration, while all those pendent from the opposite face are of the S configuration.

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.
