Cover Picture: A New Basic Motif in Cyanometallate Coordination Polymers: Structure and Magnetic Behavior of M(μ‐OH<sub>2</sub>)<sub>2</sub>[Au(CN)<sub>2</sub>]<sub>2</sub> (M=Cu, Ni) (Chem. Eur. J. 26/2006)
Bibliographic record
Abstract
Watery bridges play the key role in a new basic structural motif exhibited by M(μ‐OH2)2[Au(CN)2]2 (M=Cu, Ni) materials. This motif is unique for cyanometallate‐based polymers and rare in aqueous coordination chemistry: a 1D chain propagated by double aqua‐bridges. These metal–water chains, shown here cascading down a rock‐studded waterfall, aggregate through hydrogen bonds to form stacked ribbons in 3D. The magnetic properties of both compounds were studied by using short‐lived subatomic muons as highly sensitive local probes in zero‐magnetic field, as shown here. D. B. Leznoff, J. E. Sonier et al. describe these CuII and NiII cyanoaurate coordination polymers on page 6748 ff.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
