Abstract
Treatment of Si(OMe) 4 with three molar equivalents of 1,2-C 6 H 4 (OH) 2 (= 1,2-dihydroxybenzene) and two molar equivalents of HO(CH 2 ) n NMe 2 (n = 2, 3) in acetonitrile at room temperature yields the λ 6 Si-silicates (HO(CH 2 ) n NMe 2 H) 2 (SiL 3 ) (5: n = 2; 6: n = 3; L 2 = 1,2-C 6 H 4 (O) 2 2 (= benzene-1,2-diolato(2))). The analogous λ 6 Ge-germanates (HO(CH 2 ) n NMe 2 H) 2 (GeL 3 ) (7: n = 2; 8: n = 3) were synthesized analogously starting from Ge(OMe) 4 . Compounds 5·2CH 3 CN and 6-8 were structurally characterized by single-crystal X-ray diffraction. In addition, aqueous solutions of the Si/Ge analogs 5/7 and 6/8 were studied by NMR spectroscopy. The title compounds may be regarded as model systems for the transport and storage of silicon in biological systems and as tools to investigate biosilification.Key words: hexacoordinate silicon, hexacoordinate germanium, silicon biochemistry

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
