Abstract
In aqueous solution systems, an all-inorganic Ni 6 -added polyoxometalate (Ni 6 AP) [Ni 6 (μ 3 –OH) 3 (H 2 O) 12 (B-α-SiW 9 O 34 )] 1– ({ Ni 6 SiW 9 }, here, { Ni 6 } = Ni 6 (μ 3 –OH) 3 (H 2 O) 12 ) has been made via a hydrothermal method. By introducing inorganic boron sources, a B 3 O 3 (OH) 6 ({ B 3 }) cluster was precisely anchored onto { Ni 6 } to form a [B 3 O 3 (OH) 6 Ni 6 (μ 3 –OH) 2 (H 2 O) 8 (B-α-SiW 9 O 34 )] 3– ({ B 3 Ni 6 (OH) 2 (H 2 O) 8 SiW 9 }) through replacing four terminal water molecules and condensing with one hydroxyl of the { Ni 6 } cluster. Subsequently, the addition of further boron sources facilitated the in situ growth of B–O clusters on the basis of { B 3 Ni 6 (OH) 2 (H 2 O) 8 SiW 9 }, which resulted in the successful synthesis of {[B 7 O 8 O 2/3 (OH) 6 Ni 6 (μ 3 –OH) 2 (H 2 O) 8 (B-α-SiW 9 O 34 )] 3 } 7– ({ B 7 Ni 6 (OH) 2 (H 2 O) 8 SiW 9 } 3 or { B 21 }@{Ni 6 (OH) 2 (H 2 O) 8 SiW 9 } 3 ). It is the first all-inorganic cage cluster constructed by NiAPs and B–O clusters, which successfully realizes the inorganic borate functionalized POMs from a single cluster to a cage cluster. The central {B 7 O 8 O 2/3 (OH) 6 } 3 ({ B 21 }) cluster exhibits an uncommon cavity configuration. Meanwhile, we have conducted a discussion of the possible formation mechanism of B–O functionalized NiAPs. Furthermore, these three compounds efficiently accelerate the oxidative transformation of sulfides, and the number of B atoms in compounds relatively affects the selectivity of the products.

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
