Spectroscopic studies of trans-bis(hexafluroarsenato)tetrakis(thiazyl trifluoride)metal(II) complexes (M = Mn, Fe, Co, Ni, or Cu); crystal structure of the manganese(II) complex: an example of exceptionally short N–S bonds and of AsF6 as a unidentate ligand

Abstract

The i.r. spectra of the series [M(NSF3)4(AsF6)2](M = Mn, Fe, Co, Ni, or Cu) indicate that the compounds are isostructural, with trans-AsF6 groups co-ordinated to the metal atom, and N–S bonds appreciably stronger than in free NSF3. This is confirmed by the crystal structure of trans-[Mn(NSF3)4(AsF6)2]. It crystallises in the monoclinic space group P21/n, with a= 7.496(4), b= 10.378(5), c= 13.979(6)Å, β= 94.33(3)°, and Z= 2. The structure was refined to R= 0.048 for 1 226 diffractometer data. The metal ion is octahedrally co-ordinated, with Mn–Nav. 2.187, Mn–F 2.193(4), and N–Sav. 1.365 Å.
