Resumen

The heterobridged binuclear complexes of general formula [M2(μ-pz)(μ-SBut)(CO)2{P(OMe) 3}2] (pz = pyrazolate; M = Rh, 1; or Ir, 2) react with methyl iodide to give [M2(μ-pz)(μ-SBut)(Me)I(CO)2{P(OMe) 3}2] (M = Rh, 3; or Ir, 4). Reaction of the diiridium complexes 2 or [Ir2(μ-dmpz)(μ-SBut)(CO)2{P(OMe) 3}2] (dmpz = 3,5-dimethylpyrazolate) with diiodomethane give [Ir2(μ-pz)(μ-SBut)(μ-CH2)I 2(CO)2{P(OMe)3}2] 5 or [Ir2(μ-dmpz)(μ-SBut)(CH2I)I(CO) 2{P(OMe)3}2] respectively. The crystal and molecular structure of 5 has been determined by X-ray diffraction methods. Crystals are monoclinic, space group P21/c, with a = 11.398(1), b = 16.571(2), c = 16.274(2) Å, β = 106.87(1)°, and Z = 4. The molecule is binuclear, with the two metal centres bridged by a pyrazolate anion, a SBut group and a methylene carbon atom.
