Ce/Au(CN)<sub>2</sub><sup>–</sup>‐Based Coordination Polymers Containing and Lacking Aurophilic Interactions
Bibliographic record
Abstract
Abstract New members of the Ln[Au(CN) 2 ] 3 · 3H 2 O and [ n Bu 4 N] 2 [Ln(NO 3 ) 4 Au(CN) 2 ] series Ln = Ce (CeAu 3 and CeAu respectively) are reported herein where their synthesis, structure and photoluminescence properties are discussed. The first is a 3‐D coordination polymer with aurophilic interactions of 3.35 Å and the latter is a 1‐D coordination polymer that lacks them. At 293 K both CeAu 3 and CeAu display characteristic Ce III ‐based emission at λ max = 393 nm (5d→ 2 F J ), however in CeAu 3 Au I ‐based emission ( λ max = 410, 1 MLCT) dominates the spectrum. At 77 K however, the dominant emission is Au I ‐based with characteristic emissions of λ max = 430 nm ( 1 MLCT) and 490 nm ( 3 MLCT). The key difference in the luminescence of these two materials can be rationalized in terms of their respective structures, through either the aurophilic network and lack thereof and/or the rigidity offered in the 3‐D structure of CeAu 3 .

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
