Abstract
Summarized here are our continuous studies of the last three decades concerning syntheses of new types of complexes learned from nitrogenase and their reactivites toward dinitrogen, nitriles, and alkynes. For Mo and W dinitrogen complexes with tertiary phosphine coligands, a variety of their intriguing reactivities have been demonstrated, and novel transformations of the N 2 ligands into numerous nitrogen-containing ligands and compounds have been developed. The C≡N bond cleavage of certain nitriles also proceeds on the Mo site surrounded by tertiary phosphines. Stimulated by the sophisticated structure of the active site of nitrogenase, multinuclear metalsulfur complexes have been synthesized in rational ways. New types of stoichiometric and catalytic reactions of alkynes have been found by using the thiolato-bridged diruthenium complexes and some cubane-type sulfido clusters containing a noble metal.Key words: nitrogen fixation, molybdenum and tungsten dinitrogen complexes, ruthenium thiolato complexes, metal sulfido clusters, nitriles, alkynes.

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
