Abstract

fetched live from OpenAlex

Alkynylgold(I) complexes have been prepared from the angular bis(alkyne) MeC 6 H 3 -3,5-(CCH) 2, in which the alkyne units are rigidly fixed at an angle of 120° to each other. Reaction with [AuCl(SMe 2 )] and base yields the shock-sensitive, insoluble compound [{MeC 6 H 3 -3,5-(CCAu) 2 } n ] ( 2 ), which reacts with isocyanide, phosphine, or phosphite ligands (L) to give [MeC 6 H 3 -3,5-(CCAuL) 2 ] ( 3; L = P(OPh) 3, P(OMe) 3, PPh 3, PMePh 2, t -BuNC, MeNC). The complexes with L = P(OMe) 3, PMePh 2 exist in the solid state as infinite one-dimensional ribbon structures in which neighboring molecules are associated through secondary gold−gold bonding. Complexes with diisocyanide ligands 1,4-C 6 R 4 (NC) 2 (R = H, Me) have the formula [{MeC 6 H 3 -3,5-(CCAu) 2 (μ-LL)} n ] and are insoluble in organic solvents; they are suggested to have a zigzag polymeric structure. In contrast, complexes with diphosphine ligands (CH 2 ) n (PPh 2 ) 2 ( n = 1−6) are soluble and are suggested to be the cyclic tetragold(I) complexes of formula [{MeC 6 H 3 -3,5-(CCAu) 2 (μ-LL)} 2 ]; the ring size varies from 24 to 34, depending on n .

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.
