Unusual Structures, Phase Behavior, and Fluorescent Properties of 3-phenyl-1-(pyridin-2-yl)-1H-pyrazol-5-amine and Its’ ZnCl2 Complex
Bibliographic record
Abstract
The synthesis and single crystal structures of 3-phenyl-1-(pyridin-2-yl)-1 H -pyrazol-5-amine ( L1 ) and its complex with ZnCl 2 are reported. L1 exhibits supercooling, with a difference in melting and solidification points of over 100 o C. The complex [ L1 ZnCl 2 ] has a room-to-low temperature single crystal-to-crystal phase transition in the solid state, while a birefringent fluid phase mixed with crystalline domains is observed at high temperatures. Significant fluorescence enhancement is observed upon formation of the ZnCl 2 complex.

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.
