Experimental and theoretical studies of the d(8)-d(10) interaction betweenPd(II) and Au(I): Bis(chloro[(phenylthiomethyl)diphenylphosphine]gold(I))-dichloropalladium(II) and related systems
O. Crespo et al., Experimental and theoretical studies of the d(8)-d(10) interaction betweenPd(II) and Au(I): Bis(chloro[(phenylthiomethyl)diphenylphosphine]gold(I))-dichloropalladium(II) and related systems, INORG CHEM, 39(21), 2000, pp. 4786-4792
The reaction between thioether phosphine gold(I) precursors such as [AuCl(P
h2PCH2SPh)], 1, or [Au(Ph2PCH2-SPh)(2)]CF3SO3 and PdCl2(NCPh)(2) affords th
e new compounds [{AuCl(Ph2PCH2SPh)}(2)PdCl2], 2, and [AuPdCl2(Ph-2-PCH2SPh)
(2)]CF3SO3, 3. The crystal structure of complex 2 has the sterically unhind
ered Pd(II) and Au(I) at a distance of 314 pm. Quasirelativistic pseudopote
ntial calculations on [AuPdCl3(PH2CH2SH)(SH2)] models give short Au-Pd dist
ances at the second-order Moller-Plesset (MP2) level and long Au-Pd distanc
es at Hartree-Fock (HF) level. A detailed analysis of the Au-Pd interaction
shows dominant dispersion, some ionic contributions, and no net charge tra
nsfer between the metals.
