A Combined Spectroelectrochemical and Computational Study of the Chemically Reversible 2-Electron Reduction of [Ru<sub>4</sub>(μ-RC<sub>2</sub>R)<sub>2</sub>(CO)<sub>11</sub>] Clusters
Bibliographic record
Abstract
The 62-CVE clusters Ru 4 (μ-RC 2 R) 2 (CO) 11, which feature a dodecahedral cluster core, are readily reduced to a 64-CVE dianion in a process that is essentially chemically reversible. A combination of electrochemical, spectroelectrochemical, and computational analyses of the system indicates that the first formed dianion, which features a square planar arrangement of the metal centers with the alkyne ligands located on opposite faces of the M 4 square and oriented in a manner such that the C−C bonds are perpendicular to each other, undergoes a thermal rearrangement giving a product in which the alkyne vectors lie parallel to each other across the metal framework.

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.
