Iron complexes of the N(CH[sub 2] CH[sub 2] S)[sub 3] [sup 3–] (NS[sub 3] ) ligand with isocyanide co-ligands.

The complexes NEt[sub 4] [Fe(NS[sub 3] )(CNR)] (1), [Fe{Fe(NS[sub 3] )(CNR)}[sub 2] -S,S' ] (2), [Co{Fe(NS[sub 3] )(CNMe)}[sub 2] -S,S' ] (3), and [Ni{Fe(NS[sub 3] )(CNMe)}[sub 2] -S,S' ] (4) (R = Me, t-Bu, or C[sub 6] H[sub 11] (Cy)) have been prepared and the X-ray crystal structures of NEt[sub 4] [Fe(NS[sub 3] )(CNMe)] (1a) and [Fe{Fe(NS[sub 3] )(CNCy)}[sub 2] -S,S' ] (2c) have been determined. Mössbauer and IR spectroscopic data and room temperature magnetic moments for these complexes are reported.Key words: iron, cobalt, nickel, thiolate, isocyanide.On a préparé les complexes de NEt[sub 4] [Fe(NS[sub 3] )(CNR)] (1), [Fe{Fe(NS[sub 3] )(CNR)}[sub 2] -S,S' ] (2), [Co{Fe(NS[sub 3] )(CNMe)}[sub 2] -S,S' ] (3) et [Ni{Fe(NS[sub 3] )(CNMe)}[sub 2] -S,S' ] (4) (R = Me, t-Bu ou C[sub 6] H[sub 11] (Cy)) et on a déterminé les structures de NEt[sub 4] [Fe(NS[sub 3] )(CNMe)] (1a) et de [Fe{Fe(NS[sub 3] )(CNCy)}[sub 2] -S,S' ] (2c) par diffraction des rayons X. Pour chacun de ces complexes, on a déterminé les spectres de Mössbauer et IR ainsi que les moments magnétiques à la température ambiante.Mots clés : fer, cobalt, nickel, thiolate, isocyanure.[Traduit par la Rédaction] [ABSTRACT FROM AUTHOR]
