Abstract

fetched live from OpenAlex

The title compound is an ethanol-solvated salt, C(16)H(38)N(4)(2+) x -2C(11)H(7)O(2)(-) x -2C(2)H(6)O, in which the cation lies across a centre of inversion in P2(1)/c. The ions are linked by N-H...O hydrogen bonds [H...O = 1.70 and 2.30 A, N...O = 2.624 (2) and 3.136 (2) A, and N-H...O = 178 and 151 degrees ], and the ethanol molecule is linked to the anion by an O-H...O hydrogen bond [H...O = 1.90 A, O...O = 2.728 (2) A and O-H...O = 171 degrees ], to form a centrosymmetric five-component aggregate. C-H...O hydrogen bonds and aromatic pi-pi-stacking interactions are absent, but the aggregates are linked into sheets by a single C-H...pi(arene) hydrogen bond.

Full frame distilled prediction

Teacher imitation

Not 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.
