Syntheses and Structures of Silver(I) and Palladium(II) Complexes with Ferrocenyl-phosphonodithiolate Ligands

摘要

Coordinative interaction of [Ag(PPh_3)_2NO_3] or [Pd(MeCN)_2Cl_2] with in situ-prepared Na[FcP(OR)S_2] afforded 1 : 1 products [FcP(OR)S_2Ag(PPh3_)_2] (R = Me 1, n-Pr 2) or the 1 :2 product [{FcP(OMe)S_2}_2Pd] (3). Complexes 1 –3 were characterized by elemental analysis, mass spectrom-etry, NMR (~1H, ~(31)P) and IR spectroscopy, as well as by X-ray crystallography. The distorted tetrahedral silver(I) coordination led to non-planar and distorted four-membered AgS_2P rings in 1 and 2, whereas the square-planar palladium(II) coordination resulted in four-membered co-planar PdS_2P rings in 3.
