Synthesis and complexation studies of mesocyclic and macrocyclic polythioethers. 9. Synthesis and crystal structure of bis(1,4,7-trithiacyclodecane)palladium(II) hexafluorophosphate

Anion and Solvent Effects upon the Structures of Platinum(II) Complexes with Thiacrown Ligands: The Crystal Structures of [Pt(9S3)2](PF6)2·2 CH3NO2, [Pt(9S3)2](BF4)2·2 CH3NO2, [Pt(9S3)2](OTf)2·2 CH3NO2, and [Pt(18S6)](BF4)2

“…[19,20] Interestingly, the linkage isomer obtained for the [Pd(10S3) 2 ] 2ϩ complex, reported by McAuley, has a six-membered chelate ring between the equatorial sulfurs, while our structure contains a five-membered chelate ring between the sulfurs. The switch in linkage isomer appears to be due to packing forces associated with a particular solvent (nitromethane vs. acetonitrile); this solventϪcomplex interaction has been confirmed via low temperature 13 C NMR studies.…”

Synthesis of an acyclic diselenodithioether ligand tethered with bulky substituents and its application to the synthesis of a distorted octahedral palladium(II) complex

“…Cyclic polythioether (crown thioether) ligands such as 1,4,7-trithiacyclononane (9S3) [1,2], 1,4,7,10,13,16-hexathiacyclooctadecane (18S6) [3], and 1,4,7-trithiacyclodecane (10S3) [4,5], reportedly complexed with a palladium(II) metal to give the corresponding five-or six-coordinate palladium(II) complexes, in which the four sulfur atoms are arranged in a square planar fashion around the palladium(II) atom and the other sulfur atoms weakly coordinate to the palladium(II) atom [Pd · · · S: 2.96-3.27Å] at the axial positions.…”

Metal binding studies with macrocyclic hexathioethers: Transition metal complexes of 22S6 and 20S6

“…Ruthenium(II) has been noted as the ideal ion for stabilizing hexakis(thioether) octahedral complexes of thioethers [25,39]. For several years our group and others have studied the complexation behavior of crown thioethers towards Pd(II) and Pt(II) and the unusual structural, spectroscopic, and electrochemical properties observed in these complexes [22,40,53]. Of particular interest is the influence and control of these unusual properties by changes in the ligand structure and conformation.…”
