The Co-ordination of Small Molecules By Manganese(II) Phosphine Complexes. Part 14. Some Novel Mixed Tertiary Phosphine-t-Butyl Isocyanide Complexes of Manganese(II): t)(PPhMe2)> and t)4(PR3)2>2+ (PR3=PPhMe2, PPh2Me, PPhEt2, or PPrn3), and the X-Ray Crystal ...

The complex t)(PPhMe2)> has been prepared by reaction of with CNBu^t.In ethanol solution rearrangement occurs to give the complex t)4(PPhMe2)2> and this reacts with other phosphines to yield t)4(PR3)2>²⁺ (PR3=PPrⁿ3, PPhEt2, or PPh2Me).Air oxidation of an ethanol solution of t)4(PPhMe2)2>²⁺ produces red crystals of t)4(PPhMe2)2>2 the structure of which is reported.In the cation Mn^II is octahedrally co-ordinated and lies on a crystallographic inversion centre.The latter also relates each pair of anions which have Mn^II in tetrahedral co-oordination.The Mn-P bonds of the cation are rather short at 2.344(3) Angstroem whereas all other cation and anion dimensions are unremarkable.
