Hexakis(acetonitrile)iron(II) hexafluoroantimonate

The title compound, [Fe(C2H3N)(6)][SbF6](2), (I), synthesized by reaction of AgSbF6 with FeCl2 in CH3CN, is isostructural with the analogous nickel complex [see Leban et al. (1987), Acta Cryst. C43, 1888-1890]. The Fe II centre in the cation occupies a crystallographic (3) over bar site and is octahedrally coordinated by six acetonitrile ligands, with an Fe-N distance of 2.153 (2) Angstrom and an N-Fe-N angle of 88.05 (10)degrees. The SbF6- anion lies on a crystallographic threefold rotation axis. [GRAPHICS]
