Resumen

The preparation and properties of trinuclear complexes containing pyrazolate and chloride as bridging ligands are reported. Representative formulae are [L2M(μ-Cl)(μ-pz)Pd(μ-Cl)(μ-pz)ML2] [M = Rh, L2 = diolefin or (CO)2; M = Ir, L2 = diolefin; M = Pd, L2 = η3-C3H5 or η3-C4H7]. These complexes react with the pyrazolate anion to give trinuclear homobridged compounds of formula [L2M(μ-pz)2Pd(μ-pz)2ML2]. The crystal structure of the carbonyl derivative [(OC)2Rh(μ-pz)2Pd(μ-pz)2Rh(CO) 2] has been determined by single-crystal X-ray methods. Crystal are monoclinic, space group P21/c with cell constants a = 8.9281(5), b = 11.7961(6), c = 10.391 6(5) Å, β = 94.727(4)°, and Z = 2. The intermetallic distance palladium-rhodium is equal to 3.578 9(6) Å.
