New dinuclear and heterotrinuclear complexes containing the M2(μ-az)(μ-PPh2) core (M = Rh or Ir; az = azolate)

The heterobridged dinuclear complexes [M2(μ-Pz)(μ-PPh2) (COD2)] (M = Rh; Pz= pyrazolate (pz) (1) or 3,5-dimethylpyrazolate (dmpz) (2) (M = Ir; Pz = pz (3) or dmpz (4)) have been prepared by reaction of [M2(μ-Cl)(μ-Pz)(COD)2] with LiPPh2. Substitution of the chloride bridge in [Rh2(μ-Cl)(μ-PPh2)(COD)...

Descripción
Sumario:The heterobridged dinuclear complexes [M2(μ-Pz)(μ-PPh2) (COD2)] (M = Rh; Pz= pyrazolate (pz) (1) or 3,5-dimethylpyrazolate (dmpz) (2) (M = Ir; Pz = pz (3) or dmpz (4)) have been prepared by reaction of [M2(μ-Cl)(μ-Pz)(COD)2] with LiPPh2. Substitution of the chloride bridge in [Rh2(μ-Cl)(μ-PPh2)(COD)2] by an azolate on compound is a good method for preparing complexes [Rh2(μ-az)(μ-PPh2)(COD)2] (az = 1,2,4-triazolate (tz) (5), or tetrazolate (ttz) (6)). The preparation of the heterobridged heterotrinuclear complexes [{M(μ-pz)(μ-PPh2()COD)}2Pd] (M = Rh (7) or Ir (8)) is also reported.
