Abstract
The organometallic cationic acid [CoIII(η5-C5H4COOH)2]+ (AC) is crystallised from hydrochloric acid solutions in two polymorphic modifications of the salt [CoIII(η5-C5H4COOH)2]Cl·H2O, ACCl·H2Ocube and ACCl·H2Osword. On the other hand, ACCl·H2Osword is isomorphous with the triply-hydrated zwitterion [CoIII(η5-C5H4COOH)(η5-C5H4COO)], ZW·3H2O. ACCl·H2Osword, ACCl·H2Ocube and ZW·3H2O are all converted into the anhydrous form [CoIII(η5-C5H4COOH)(η5-C5H4COO)], ZW, upon thermal treatment. The structural relationship between the ionic and neutral systems and their interconversion have been investigated with a combination of solid-state techniques (single crystal and powder X-ray diffraction, thermogravimetric analysis, mass spectrometry and solid state 13C CP/MAS NMR).

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
