Abstract
The reactions of blue luminescent ligands 1,3-bis(7-azaindolyl)benzene (BabH), 1-bromo-3,5-bis(7-azaindolyl)benzene (Br−BabH), and 1,3,5-tris(7-azaindolyl)benzene (TabH) with K 2 PdCl 4 and K 2 PtCl 4 have been investigated. Five new luminescent cyclometalated palladium(II) and platinum(II) complexes Pd(Bab)Cl ( 1 ), Pt(Bab)Cl ( 2 ), Pd(Br−Bab)Cl ( 3 ), Pt(Br−Bab)Cl ( 4 ), and Pd 3 Cl 4 (Tab) 2 ( 5 ) have been synthesized and fully characterized. The molecular structures of 1 and 2, and 3 and 4, are similar. There are however significant variations in the solid-state structures and luminescence of 1 and 2, and 3 and 4 . EHMO calculations revealed that it is most likely that the electronic transitions in the Pt(II) complexes are π to π* transitions with significant contributions from d π lone pairs of the Pt(II) center in the π level, and the electronic transitions in the Pd(II) complexes are either d( z 2 ) to π* charge-transfer transitions or π to π* transitions similar to the Pt(II) complexes.

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
