Mono and Poly‐nuclear Silver(I) Complexes with Thiosaccharin and Triphenylphosphine. Synthesis, Spectroscopic and Structural Characterization of Thiosaccharinato‐bis(triphenylphosphine)silver(I) and Tetrakis{thiosaccharinato(triphenylphosphine)silver(I)}
Bibliographic record
Abstract
Abstract The reaction of Ag 6 (tsac) 6 ( 1 ) (tsac = thiosaccharinate anion) with triphenylphosphine gives rise to the already reported [Ag(tsac)(PPh 3 ) 3 ] complex ( 2 ) and to two new silver‐thiosaccharinate‐phosphine complexes, [Ag(tsac)(PPh 3 ) 2 ] ( 3 ) and [Ag 4 (tsac) 4 (PPh 3 ) 4 ] ( 4 ) (PPh 3 = triphenylphosphine). Spectroscopic characterization was carried out using IR, UV‐Visible and NMR techniques and confirmed by single crystal X‐ray diffraction. In each complex a singular coordination mode for the thiosaccharinate ligand is observed. The most important features of the different coordination modes of the thionates are discussed. Compound 3 crystallizes in monoclinic system, space group Pn, with a = 11.2293(3) Å, b = 12.7282(3) Å, c = 13.6056(4) Å, β = 94.985(2)°, Z = 2; while crystals of compound 4 are monoclinic, space group P2 1 /n, a = 15.024(3) Å, b = 14.681(3) Å, c = 21.914(4) Å, β = 95.31(3)°, Z = 2. The coordination around the silver atoms in both complexes consists of almost trigonal‐planar arrangements, AgP 2 S in 3 and AgS 2 P in 4 .

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; both teacher heads agree on what is shown here.
