Bibliographic record
Abstract
The title compound, (C 6 H 14 NO 2 ) 2 [SnCl 6 ]·2H 2 O, features L-leucinium cations adopting extended conformations, which maximizes the separation between the methyl groups [–CH(CH 3 ) 2 ] and the polar NH 3 + and COOH moieties. Additionally, an intramolecular hydrogen bond between the ammonium (NH 3 + ) group and the carboxyl group induces a slight reduction in the C—C—N bond angles, with an average value of 106.5°, compared to the ideal tetrahedral angle of 109.5°. The NH 3 + group is nearly coplanar with the C—C—C—C carbon chain in both fragments, whereas the carboxyl (COOH) group and the methyl group at the C5 position deviate significantly from this plane. The octahedral complex anion is close to regular. In the crystal, an extensive network of hydrogen bonds links the components into a three-dimensional network.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
