Abstract:
An excess of PhEH (E = S, Se) reacts with
Pd2(PCy2H)2(mu-PCy2)(mu-eta3-C3H5) causing, by protonation of the
bridging ligands, the disruption of the dinuclear unit and the formation
of the monomers trans-{[Pd(EPh)2(PCy2H)2]. The isolated monomers were
reacted with the same pi-allyl dimer providing a synthetic route to the
clusters [Pd3-(mu-PCy2)2(mu-EPh)(PCy2H)2(EPh)]; these mixed-valence
triangulo complexes exhibit high stability both in the solid state and
in solution, but are reactive toward weak proton donors. Reaction with
an excess of PhEH and PCy2H rapidly and quantitatively gives the
monomers trans-[Pd(EPh)2(PCy2H)2]. All complexes were characterized by
multinuclear NMR analyses. [Pd3(mu-PCy2)2 (mu-SPh)(PCy2H)2(SPh)]
crystallizes in the Pnma space group (orthorhombic, Z = 4) with the
following unit cell dimensions: a = 13.587(4), b = 25.231(8), c =
18.306(6) angstrom.}
