The heterobridged dinuclear complexes [M(2)(mu-Pz)(mu-PPh(2))(COD)(2)] (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 [M(2)(mu-Cl)(mu-Pz)(COD)(2)] with LiPPh(2). Substitution of the chloride bridge in [Rh-2(mu-Cl)(mu-PPh(2))(COD)(2)] by an azolate on compound is a good method for preparing complexes [Rh-2(mu-az)(mu-PPh(2))(COD)(2)] (az = 1,2,4-triazolate (tz) (5), or tetrazolate (ttz) (6)). The preparation of the heterobridged heterotrinuclear complexes [M(mu-pz)(mu-PPh(2))(COD))(2)Pd] (M = Rh (7) or Ir(8)) is also reported.
