Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

The diorganoselenide [Me2C(OH)CH2]2Se (1) was prepared by reacting the in situ obtained Na2Se with 1‐chloro‑2‐methyl‐2‐propanol. Reactions of 1 and [2-(Me2NCH2)C6H4]2Se (2) with appropriate silver(I) salts in 1:1 molar ratio resulted in metal complexes of type [Ag(X)Se{CH2C(OH)Me2}2] [X = OSO2CF3 (OTf) (3), OClO3 (4)] and [Ag(X)Se{C6H4(CH2NMe2)-2}2] [X = OSO2CF3 (5), ONO2 (6)], respectively. The ligand 1 and the silver complexes were investigated by appropriate spectroscopic methods, both in solution and in solid state: multinuclear NMR (1H, 13C, 19F, 77Se), ESI+ mass spectrometry, IR spectroscopy and molar conductivity. The metal complexes behave as 1:1 electrolytes in 10−3 MeOH solutions, while in solid state the anionic ligands behave as monodentate moieties. Complexes 4 and 5 were investigated by single‐crystal X‐ray diffraction. The crystal of 4 contains two similar independent molecules, 4a and 4b, for which was observed the migration of one OH hydrogen from ligand 1 to the OClO3 group, thus resulting in [Ag(HClO4)Se{OCCH2Me2}{(OH)CCH2Me2}], where ligand 1 behaves as an O,Se monometallic biconective moiety. In 5 the ligand 2 acts as a N,Se,N monometallic triconective moiety. In both compounds Ag(I) is surrounded by the donor atoms in a trigonal pyramidal coordination geometry. Strong Se→Ag intermolecular interactions in 4 resulted in 1D coordination polymers built by 4a and 4b molecules, respectively, while in the crystal of 5 no interaction between heavy atoms was observed. Supramolecular networks based on H‧‧‧O contacts are formed in both compounds.

Full frame distilled prediction

Teacher imitation

Not 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.
