Preparation and Crystal Structure of the Unusual Palladium(II) Chloride/Optically Active Sulfoxide Complex: µ-[(R,R)-1,5-Bis{o-(p-toluenesulfinyl)phenoxy}-3-oxapentane]-bis(µ-chloro)-dichlorodipalladium Dichloromethane Solvate, [Pd₂C_l4(C₃₀H₃₀O₅S₂)].(CH₂Cl₂)₂

Abstract

A complex between palladium(II) chloride and the optically active podand , (S,S)-1,5-bis[o-(p- toluenesulfinyl ) phenoxy ]-3-oxapentane, has been prepared and is shown to contain two equivalents of palladium(II) chloride to one equivalent of the podand. Crystal structure analysis shows each of the sulfur atoms in the sulfoxide groups is coordinated to a palladium atom, and the palladium atoms are also linked through chloride bridges. Crystal data: a 14.878(2), b 17.226(3), c 8.178(1) Ǻ, β 103.30(1)°; P2₁; Z 2.
