The reactivity of two paramagnetic nickel(I) compounds, CpNi(NHC) (where Cp = cyclopentadienyl; NHC = 1,3-bis(2,4,6-trimethylphenyl) imidazol-2-ylidene (IMes) or 1,3-bis(2,6-diisopropylphenyl) imidazol-2-ylidene (IPr)), towards [Na(dioxane)(x)][PnCO] (Pn = P, As) is described. These reactions afford symmetric bimetallic compounds (mu(2):eta(2),eta(2)-Pn(2)){Ni(NHC)(CO)}(2). Several novel intermediates en route to such species are identified and characterised, including a compound containing the PCO- anion in an unprecedented mu(2) :eta(2),eta(2)-binding mode. Ultimately, on treatment of the (mu(2) :eta(2),eta(2)-Pn(2)){Ni(IMes)(CO)}(2) compounds with carbon monoxide, the Pn(2) units can be released, affording P-4 in the case of the phosphorus-containing species, and elemental arsenic in the case of (mu(2) :eta(2),eta(2)-As-2){Ni(IMes)(CO)}(2).
