Synthesis and Characterization of Mixed Ruthenium/Platinum μ<sub>4</sub>-Phosphinidene, Phosphorus Monoxide, and Related Clusters
Bibliographic record
Abstract
The mixed-metal cluster complexes [Ru(4)(CO)(12)Pt(CO)PPh(3)(mu(4)-PR)] [R = N(i)Pr(2) (1), F (3)] were formed by capping the Ru(3)P face of the nido clusters [Ru(4)(CO)(13)(mu(3)-PR)] with the labile Pt(0) reagent [(eta(2)-C(2)H(4))Pt(PPh(3))(2)]. The aminophosphinidene complex 1 undergoes acid hydrolysis to yield the PO complex [Ru(4)(CO)(12)Pt(CO)PPh(3)(mu(4)-PO)][H(2)N(i)Pr(2)] (4). The fluorophosphinidene cluster 3 reacts with ethanol to form the alkoxyphosphinidene complex [Ru(4)(CO)(12)Pt(CO)PPh(3)(mu(4)-POEt)] (5). Comparison of spectroscopic and structural data for clusters 1, 3, 4, and 5 reveals the remarkable effects of the mu(4)-phosphinidene and phosphorus monoxide ligands on cluster bonding.

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.
