Structural features of silver(I) and copper(I) bis(thiophene-2-carbaldehyde imine) trifluoromethanesulfonate complexes in the solid state and in solution: crystal structures of [Ag{Th-2-CH:N-(S)-CHMePh}2](O3SCF3) and [Cu{5-Me-Th-2-CH:N-iso-Pr}2](O3SCF3) and a proton, fluorine-19 and silver-109 NMR study

From the 1:2 molar reactions of M(O 3 SCF 3 ) [M=Ag(I), Cu(I)] with the NS donor ligand system 5-R-Th-2-CH=N-R' (R=H, Me, t-BuMe 2 Si; R'=i-Pr, t-Bu, CH 2 -t-Bu, (S)-CHMePh) stable [M{5-R-Th-2-CH=N-R'} 2 ] (O 3 SCF 3 ) complexes were obtained. X-ray crystal structures of [Ag{Th-2-CH=N-(S)-CHMePh} 2 ] (O 3 SCF 3 ) and [Cu{5-Me-Th-2-CH=N-i-Pr} 2 ] (O 3 SCF 3 ) have been determined. Their basic molecular structures are isostructural, showing complex cations and noncoordinating O 3 SCF 3 − anions. The silver(I) compound crystallizes in space group C2 with a monoclinic cell
