Resumen

Complexes [M2(μ-Cl)2(diolefin)2] (M = Rh or Ir; diolefin = cyclo-octa-1,5-diene (cod), norborna-2,5-diene (nbd)) react with lithium N-benzyl-2-imidazolate (LiBzim) to yield dinuclear [M2(μ-Bzim-N3,C2)2(diolefin)2] [M = Rh, diolefin = cod (1), nbd (2); M = Ir, diolefin = cod (3)]. Carbon monoxide reacts with diethyl ether suspensions of [M2(μ-Bzim-N3,C2)2(diolefin)2] to afford the tetracarbonyl complexes [M2(μ-Bzim-N3,C2)2(CO)4][M = Rh (4), Ir (5]. In the crystal structure of dinuclear [Ir2(μ-Bzim-N3,C2)2(CO)4], organocarbonyliridium(I), the Ir atoms exhibit different coordination environments: one Ir coordinates two CO groups and two N atoms of the imidazolate rings, and the other Ir coordinates two CO groups and two C atoms of the imidazolate rings. © 1994.
