Dinitramidoborates: A Fascinating Case of Competing Oxygen and Nitrogen Donors and Tautomerism
Bibliographic record
Abstract
Abstract Reactions of the BH 4 − anion with equimolar amounts of HN(NO 2 ) 2 or of BH 3 ⋅THF with K[N(NO 2 ) 2 ] − produced a mono‐substituted [BH 3 N(NO 2 ) 2 ] − anion, which contains a B−N connected dinitramido ligand. The reaction of BH 4 − with two equivalents of HN(NO 2 ) 2 afforded the di‐substituted borate anion consisting of two isomers, one with both nitramido ligands attached to B through N and the other one with one ligand attached through N and the other one through O. The disubstituted dinitramidoborates are marginally stable under ambient conditions, and the isomer with two N‐connected ligands was characterized by its crystal structure. A tri‐substituted borate was tentatively identified by NMR in the reaction of BH 4 − with a large excess of HN(NO 2 ) 2 . All of the anions are highly energetic. Theoretical calculations show that the energy differences between the B−N and B−O tautomers are small, explaining the formation of both.

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.
