Abstract
Rhombohedral crystal phase of CuCN forms irreversibly on heating a mixture of its orthorhombic and monoclinic phases to 593 K. In its space group, $R3m$ $(a=b=0.6026 \mathrm{nm},$ $c=0.4823 \mathrm{nm},$ $\ensuremath{\alpha}=\ensuremath{\beta}=90\ifmmode^\circ\else\textdegree\fi{},$ $\ensuremath{\gamma}=120\ifmmode^\circ\else\textdegree\fi{},$ $Z=3,$ ${V}_{0}=0.1516 {\mathrm{nm}}^{3},$ and ${D}_{x}=2.94 {\mathrm{g}/\mathrm{c}\mathrm{m}}^{3}),$ positions of C and N atoms are disordered, and therefore orientations of the CN group in the (N-Cu-C) chain structure are random. Its heat capacity increases in the manner of a sigmoid shape over the 350--380 K range, analogous to that observed on kinetic unfreezing of a canonical glass, as does that of a mixture of crystal phases obtained by flocculation process. The CuCN phase appears as the simplest orientational glass whose state is trapped in a deep minimum with a corrugated bottom, and each corrugation corresponding to one configurational excitation.

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; both teacher heads agree on what is shown here.
