摘要：

The preparation of new mononuclear and dinuclear compounds is reported. The complex [IrH2(Me2CO)(HpzXPPh3)2]BF4 (1) reacts with several donors, yielding the mononuclear complexes [IrH2(Hpz)(LXPPh3)2]BF4 (L = CO (2), P(OMe)3 (3), CH3CN (4) or Hpz (9)). Treatment of 9 with a methanol solution of KOH affords [irH2(PZXHpz)(PPh3)2] (10) from which the pyrazolate ligand can be displaced by chlorine (14) or acetate (19) groups. Treatment of 3, 10, 14 or 19 with the dimerS [M2(mu-OMe)2 (eta4 -diolefin)2] (M = Rh or Ir; diolefin = cycloocta-1,5-diene or tetrafluorobenzobarrelene) leads to the heterodinuclear compounds containing the moiety ''Ir(mu-X)(A-pz)(M'' M = Rh or Ir; X = H, pz, Cl or OCOCH 3). The reaction of 1 with KOH affords the homodinuclear complex [{IrH2(mu-pz)(PPh2)2}2] (7) which upon treatment with a stoichiometric amount of HBF4 in diethyl ether gives [IrH2(Hpz)(PPh3)2]BF4 (8).
