Di-μ-α-pyrrolidinonato-bis[<i>cis</i>-diammineplatinum(II)] sulfate monohydrate as a head-to-head isomer
Bibliographic record
Abstract
In the title compound, [PtII2(C4H6NO)2(NH3)4](SO4)·H2O, the intradimer PtII—PtII distance is 2.9749 (11) Å, which is clearly shorter than the value of 3.029 (2) Å reported for a different salt of the same cation, viz. [PtII2(C4H6NO)2(NH3)4]2(PF6)3(NO3)·H2O [Matsumoto et al. (1989). Inorg. Chem. 28, 2959–2964]. The two Pt coordination planes are inclined to each other by 29.9 (5)°, and the average torsional twist of the ligands about the Pt—Pt axis is estimated as 4.3 (8)°.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
