Syntheses, crystal structures and properties of sterically congested heteroleptic complexes of group 10 metal ions with p-tolylsulfonyl dithiocarbimate and 1,2-bis (diphenylphosphino) ethane

The synthesis and characterization of three new heteroleptic complexes of nickel(II), palladium(II) and platinum(II) with p-tolylsulfonyl dithiocarbimate and 1,2-bis (diphenyl phosphine) ethane (dppe) ligands are reported. The rare anagostic C-H⋯M interactions in these mixed dppe-dithiocarbimate complexes are deduced for the first time by single crystal X-ray diffraction. These species exhibited luminescence properties in solution at room temperature.
