Synthesis, Crystal Structure and Thermal Stability of A Platinum-Based Anti-Tumour Drug Nedaplatin
Bibliographic record
Abstract
The nedaplatin has been synthesized by a new technique,the yield rate is about 65%,the content of pure product is above 99%. Its structure was characterized by elemental analysis,IR,MS,thermal analysis and X-ray diffraction single crystal structure analysis. Its crystal belongs to orthorhombic space group P212121 with a= 0.562 93(6) nm,b=0.728 53(8) nm,c=1.411 07(16) nm. The PtⅡ atom is coordinated by two N atoms of ammine and two O atom of carboxyl group and hydroxy,forming a sqare-planar environment. The glycolate dianion forms a five-membered chelate ring,coordinating to the Pt(Ⅱ)ion not only at an O atom of the carboxyl group but also at the hydroxy. The results of TG-DTA analysis show that the nedaplatin was stable under 180 ℃. CCDC:706387.

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.
