Abstract
The synthesis and characterisation (IR, NMR, HR-MS, and X-ray crystallography) of six oxazoline Zn complexes, containing enolate ligands derived from a series of ( Z)-1- R-2-(4′,4′-dimethyl-2′-oxazolin-2′-yl)-eth-1-en-1-ols ( R = C 6 H 5 , C 6 H 4 - p-NO 2 , C 6 H 4 - p-OCH 3 , CF 3 , CH 3 , or CMe 3 ) is detailed. All derivatives are air-stable solids of formula Zn( L n ) 2 and are formed in the presence of the title ligands and NEt 3 . Reasonable yields (53%–82%) are obtained with the exception of R = CMe 3 (9%); in this case, by-product formation and high solubility affected complex isolation. Crystallographic characterisation reveals that in all cases the ligands are bound in a κ 2 -N ,O-bonding motif. Little structural diversity is noted within the series; these complexes are further placed into structural context with related Zn materials containing oxazoline, phenolate, and (or) Schiff base ligands.

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 it
