Abstract
An acentric alkali metal borate, Li 6 [{BO 3 }{B 15 O 21 (OH) 6 }] ( 1 ), has been made. The alternation of BO 3 triangles and [B 15 O 24 (OH) 6 ] 9– clusters constructs a two-dimensional (2D) anionic framework of 1 with larger 15-membered ring (MR) windows, of which the fan-like [B 15 O 24 (OH) 6 ] 9– cluster is formed by the connection of two [B 9 O 18 (OH) 3 ] 12- units through edge-sharing. The [B 9 O 18 (OH) 3 ] 12- cluster is composed of the same three [B 3 O 7 (OH)] 6– units and one [B 3 O 9 ] 9– unit sharing BO 4 tetrahedra. Notably, the hydroxylated form of the [B 15 O 24 (OH) 6 ] 9– cluster in 1 was first found in the acentric borate. The layers are further assembled into a three-dimensional (3D) supramolecular framework through hydrogen bonding and LiO n polyhedra. The ultraviolet–visible (UV–vis) absorption spectrum indicates that the band gap of 1 is 4.49 eV, indicating that it is a wide-band semiconductor. Second-harmonic generation (SHG) measurements reveal that 1 has a moderate second-harmonic signal, 1.3 times that of KH 2 PO 4 (KDP), and is phase-matched.

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
