Reaction of trans- with the zwitterion S2C-PR'3 affords the complexes trans-ClO4 (M= Pd; R3=R'3= Et3, Bu3 or Et2Ph; R= Bu, R'= cyclo-C6H11; R= Ph, R'= Et or cyclo-C6H11; M= Pt, R=R'= Et or Bu). trans-ClO4 is also given by reaction of ClO4 with CS2.Reaction of (bipy= 2,2'-bipyridyl) with S2C-PR'3 affords ClO4 (M=Pd or Pt; R'=Et, Bu, or cyclo-C6A11).A crystallographic study of trans-ClO4 (as its 1:1 chloroform solvate) shows that the cation contains a unidentate triethylphosphoniumdithiocarboxylate ligand, and 31P n.m.r. spectra of all products with two terminal phosphine ligands are consistent with trans stereochemistries.Crystals of trans-ClO4*CHCl3 are monoclinic, space group P2¹/a, with a=14.596 5(18), b=15.356(3), c=19.324 2(16) angstroem, β=109.257(8) deg, and Z=4.Using 4 093 amplitudes the structure has been refined to R=0.1049.The non-bonding Pd...S distance is 3.644(4) angstroem.
