Resumen

The preparation and properties of binuclear complexes containing the pyrazolate and azide groups as bridging ligands are reported. Representative formulae are: M2(μ-pz)(μ-N3)(CO)4, M2(μ-pz)(μ-N3)- (COD)2 (M = Rh or Ir), (CO)2Rh(μ-pz)(μ-N3)ML2 (M = Rh, L2 = COD, M = Ir, L = CO) and (η3-C3H5)- Pd(μ-pz)(μ-N3)Rh(CO)2. The crystal and molecular structure of the latter complex has been determined by single-crystal X-ray methods. Crystals are monoclinic, space group C2/c with cell constants a = 18.4750(10), b = 10.0351(3), c = 13.6399(6) Å, α = 90, β = 100.022(4), γ = 90°, and Z = 8. The final R and Rw values were 0.051 and 0.062 for 1417 observed reflexions. This binuclear compound packs in the crystal zig-zag chains of rhodium atoms, along the c axis, wtth intermolecular Rh···Rh contacts of 3.290(1) and 3.604(1) Å. The Rh···Rh···Rh angle is 163.16(4)°. © 1987.
