Abstract
The dilithio boraamidinates {Li2[RB(NtBu)2]}x (R = Me, nBu) are obtained by the reaction of B[N(H)tBu]3 with 3 equivalents of LiR. The X-ray structures of the dimer (R = nBu) and trimer (R = Me) consist of distorted Li4N4 cubes or Li6N6 hexagonal prisms capped by two or three BR groups, respectively. The lithiation of the dimers {M[N(H)tBu]3}2 (M = Al, Ga) with LiR (R = tBu, Me) gives rise to complexes of the type {Li[Al(NtBu)(NHtBu)2]}2(LiR) [R = tBu, N(H)tBu] in which monomeric LitBu or LiN(H)tBu units are trapped by the dilithiated M2N6 template. The centrosymmetric dimer {THF Li3[Si(NiPr)3(NHiPr)]}2, formed by trilithiation of Si[N(H)iPr]4 with LinBu, forms a bicapped hexagonal prism. The tetraazasilicate (Et2O-Li)4[Si(Nnaph)4] is prepared by the reaction of SiCl4 with 4 equiv. of Li2(Nnaph). Treatment of OP[N(H)tBu]3 with an excess of LinBu yields the dilithiated derivative {(THF)Li2[OP(NtBu)2(NHtBu)]}2 with a box-shaped structure.

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; a candidate call from one teacher head, not a consensus.
