Abstract
Abstract Five new Cu I /[Au(CN) 2 ] − ‐based coordination polymer materials—Cu(py) 2 [Au(CN) 2 ] ( 1 ), Cu(PPh 3 )(MeCN)[Au(CN) 2 ] ⋅ MeCN ( 2 a ), Cu(PPh 3 )(MeCN)[Au(CN) 2 ] ( 2 b ), Cu 3 (THT) 4 [Au(CN) 2 ] 3 ( 3 a ) and Cu(THT)[Au(CN) 2 ] ( 3 b )—were prepared and characterized in terms of their structural and photoluminescence properties, and thermal stability (py=pyridine, THT=tetrahydrothiophene). While 1 and 2 a / 2 b adopted one‐dimensional zig‐zag chain structures with no Au ⋅⋅⋅ Au (aurophilic) bonding, 3 a and 3 b exhibited much more complex three‐dimensional frameworks featuring numerous aurophilic interactions; bridging THT units formed either eight‐membered Cu 4 S 4 rings ( 3 a ) or helical (Cu/S) n chains ( 3 b ). When these materials are excited using a broad‐band UV source (365 nm), they each emit light of a distinct colour (except for 2 a ): light green for 1 , pale blue for 2 b , deep blue for 3 a , and violet for 3 b ( λ max =506 nm ( 1 ), 464 nm ( 2 b ), 457 nm ( 3 a ) and 404 nm ( 3 b )). The emission band in 1 , 2 b and 3 b was assigned to Cu I /ligand/CN − ‐based MLCT transitions, while the emission band of 3 a appears to be influenced by the presence of the aurophilic interactions in the structure. Materials 1 and 3 a lose their bound pyridine and THT, respectively, at 110 and 95 °C, respectively, indicating their potential utility as sensory materials.

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
