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

“…C, H, N and S analyses were carried out with a PerkinϪElmer 2400 microanalyser. Mass spectra were recorded [14] [O(AuPPh 3 ) 3 ]ClO 4 , [15] [Au(C 6 F 5 )(tht)], [16] [Au(C 6 F 5 ) 3 (OEt 2 )], [17] [Au(C 6 F 5 ) 2 Cl] 2 [18] and [Ag(OTf)(PPh 3 )] [19] were prepared according to published procedures. All other reagents were commercially available.…”

Gold and Silver Complexes with the Ligands N‐[Bis(isopropoxy)thiophosphoryl]thiobenzamide and N‐[Bis(isopropoxy)thiophosphoryl]N′‐phenylthiourea

“…The ligands (HL 1 ) [4] and (HL 2 ) [5] and the starting materials [Au(acac)(PPh 3 )], [33] [O{Au(PPh 3 )} 3 ]ClO 4 , [34] [Au-(acac)(C 6 F 5 ) 2 ], [35] PPN[Au(acac) 2 ], [33,36] [Ag(TfO)(PPh 3 )], [37] [Ag(TfO)(PPh 3 ) 2 ] [37] were synthesized according to literature methods. [Au(TfO)(PPh 3 )] was synthesized from [AuCl(PPh 3 )] [38] and AgTfO in dichloromethane.…”

Striking ligand-disproportionative Cl/aryl scrambling in a simple Au(iii) system. Solvent role, driving forces and mechanisms

“…The work presented here started because of a casual discovery when we wanted to prepare stable gold (III) complexes containing the cis-Au III (Rf) 2 fragment (Rf = C 6 F 3 Cl 2 -3,5). The syntheses of trans-[Au III (Pf) 2 X 2 ] -, 6 cis-[Au III (Pf) 2 X 2 ] -, 6 and (µ-Cl) 2 [Au(Pf) 2 ] 2 , 7,8 complexes had been reported forty years ago, but we prefer to use Rf derivatives because they greatly simplify the 19 F NMR spectra (there is no intra-ring 19 F- 19 F coupling in C 6 F 3 Cl 2 -3,5). 9 This NMR simplification is useful to separate signals that with C 6 F 5 can overlap in mixtures due to their multiplicity.…”
