Hydrazide Salts of Di‐Picric Acid as Dense and Insensitive Energetic Materials
Bibliographic record
Abstract
Abstract Energetic dipicrate hydrazide salts were synthesized by combining picric acid (PA) as anion and carbohydrazide and oxalyldihydrazide as cations in stoichiometric amounts (2 : 1 mol ratio). The structures of 2,2′‐carbonyldi(hydrazin‐1‐ium) bispicrate ( 1 ) and 2,2′‐(1,2‐dioxoethane‐1,2‐diyl)di(hydrazin‐1‐ium) bispicrate ( 2 ) were investigated by single‐crystal X‐ray diffraction analysis, illustrate that both crystals of 1 and 2 belong to the monoclinic system (space group, C2/c). The prepared salts were thoroughly characterized using NMR, IR spectroscopy, elemental analysis, and thermogravimetric‐differential thermal analysis (TG‐DTA). The detonation velocities and pressures of salts 1 (8.02 km/s, 27.8 GPa) and 2 (8.23 km/s, 30.5 GPa) were computed by using EXPLO5 code. They exhibit high density, acceptable oxygen balance, good detonation properties and admirable thermal stability.

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.
