The tetrahedral tetrakis(phosphine) complex [bis(diphenylphosphino)butane-P,P]nickel(0)-benzene (1/2.5)

A. J. Edwards, M. Retbøll and E. Wenger

Abstract: The nickel(0) complex [Ni(dppb)₂]·2.5C₆H₆ [dppb = Ph₂P(CH₂)₄PPh₂ or C₂₈H₂₈P₂] was obtained from reaction of the boronic ester nickel(II) complex [NiBr{C₆H₄B(O₂C₂Me₄)}(dppb)] with KO^tBu. The nickel metal centre is in a tetrahedral environment characteristic of NiP₄ species. Each asymmetric unit contains 2.5 disordered molecules of benzene and satisfactory refinement was achieved after removal of the solvent void contribution from the data. A mixed anisotropic/isotropic model was used for the non-H-atom sites.
