Solution and solid-state structures of dibenzylamino calix[4]arene with complexed solvent molecules
Bibliographic record
Abstract
The solution and solid state structures of 1,3-dibenzylamino calix[4]arene were investigated via NMR and X-ray crystallography for MeCN, ethanol, hexane, THF, chloroform and toluene solvents. Analysis of the obtained structures show a symmetric flattening/pinching of the calixarene for solvents with a roughly cylindrical shape (MeCN, ethanol, hexane) and an asymmetrical flattening of the cone for more anisotropic, flat solvents, such as THF or toluene. Due to the deviation from planarity of the N2O2 fragment in the latter case, these solvents might be best suited for the preparation of octahedral or tetrahedral metal complexes, while the former would be more suitable for the preparation of square-planar complexes.

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.
