Resumen
The formation and properties of the trinuclear heterobridged complexes of general formula [Pd{Rh(μ-pz)(μ-SBut)L2}2] [L2 = cycloocta-1,5-diene 1; L2 = (CO)2 2; L2 = CO, PPh3 3 and L2 = CO, P(OMe)3 4; pz = pyrazolate] are reported. Complexes 2 and 4 react with molecular iodine to give the compounds [Pd{Rh-(μ-pz)(μ-SBut)I2L2}2] [L2 = (CO)2 5 and L2 = CO, P(OMe)3 6]. The structure of [Pd{Rh(μ-pz)(μ-SBut)(CO)2}2] 2 has been determined by X-ray diffraction methods. The trinuclear complex is centrosymmetric with the Pd atom lying on the centre of symmetry. The Rh and Pd atoms, separated by 3.686(1) Å, are connected by a double bridge, the pyrazolate ligand bridging through the two N atoms and the SBut ligand bridging through the S atom.
