Our group is interested in heteroleptic Pt(II) and Pd(II) complexes containing the thiacrown 9S3 (1,4,7-trithiacyclononane) with triphenyl Group 15 donor ligands. These complexes have the general form [M(9S3)(L)2]2+ where M is Pt(II) or Pd(II) and L is AsPh3. In this study, we report the new triphenylarsine analogues to compare their chemical properties with the known triphenylphosphine complexes. The two arsine complexes have been fully characterized by a variety of spectroscopic analyses including multinuclear NMR. We have also obtained the structure of [Pt(9S3)(AsPh3)2](PF6)2 by single crystal X-ray diffraction. The structure shows an unusual trigonal bipyramid around the platinum center, in contrast to the square pyramidal geometry typically observed in these 9S3 complexes.
