Synthesis, structure and redox behaviour of gold and silver complexes with 3-ferrocenylpyridine

The Role of Secondary Interactions in Group 11 Metal Complexes Containing the Ferrocene Ligand FcCH2NHpyMe in Supramolecular Structures

“…Few examples of compounds with the N pyridinic ϪAuϪC 6 F 5 moiety have been characterised by X-ray analysis and this value is shorter than the AuϪN bond length of 2.124(15) Å in [Au(C 6 F 5 )(3-Fcpy)] (3-Fcpy ϭ 3-ferrocenylpyridine). [12] It is similar, however, to that in [Au(C 6 F 5 )(3-Mepy)] (2.066 Å ) [2a] or the AuϪN(sp 2 ) value of 2.069(5) Å found in [Au(C 6 F 5 )(N 2 C 2 Ph 4 )]. [13] The AuϪC distance is 1.988(5) Å and resembles the values found in the complexes cited above.…”

“…At Ϫ55°C the broad singlet from 3 splits into two doublets because of the coupling with the 109,107 Ag nuclei. The positive liquid secondaryion mass spectra (LSIMSϩ) exhibit the molecular peaks at m/z (%) ϭ 917 (5) [2] or 825 (12) . In the 1 H NMR spectrum of 6 the typical resonances for the ferrocenyl, methyl and methylene (as a doublet) protons are apparent.…”

Supra-molecular synthons based on gold…π(arene) interactions

“…Zero-dimensional aggregation is also found in the structure of (3-ferrocenylpyridine)pentafluorophenylgold(I) [36] (Fig. 8a).…”

Synthesis, physical and antimicrobial studies of ferrocenyl-N-(pyridinylmethylene)anilines and ferrocenyl-N-(pyridinylmethyl)anilines

“…Studies on ferrocenylpyridines only began in the recent past and their properties have not been exhaustively described and their optimal potential usage has not hitherto been explored. 42 Furthermore, there are limited precedents, especially when compared to the ferrocenylphosphine ligands where extensive work has been carried out as independently RESEARCH ARTICLE E.M. Njogu, B. Omondi and V.O. Nyamori, 51 S. Afr.…”
