Syntheses and structures of silver(I) and palladium(II) complexes with ferrocenyl-phosphonodithiolate ligands

Abstract

Coordinative interaction of [Ag(PPh3)2NO3] or [Pd(MeCN)2Cl2] with in situ-prepared Na[FcP-(OR)S 2] afforded 1 : 1 products [FcP(OR)S2Ag(PPh 3)2] (R = Me 1, n-Pr 2) or the 1 : 2 product [{FcP(OMe)S2}2Pd] (3). Complexes 1-3 were characterized by elemental analysis, mass spectrometry, NMR (1H, 31P) 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 PdS2P rings in 3. © 2010 Verlag der Zeitschrift für Naturforschung, Tübingen.
