A new form of coordination of the versatile ligand hexathia[18]crown-6 is found in the title compounds: Pd or Pt is coordinated to four S atoms in a square planar fashion; only long range weak axial interactions are observed with the two remaining S atoms of the macrocycle. That is, the macrocycle does not behave like a crown ether.
