The synthesis and 119Sn NMR characteristics of new five-coordinate tris(trichlorostanato) complexes of Rh^I, Ir^I and Pt^II are reported.The Rh^I and Ir^I complexes are complex dianions of the form (PPN)2 where L can be CO, C<*>N(cyclohexyl) or L2, a diolefin such a 1,5-COD or NBD (norbornadiene).The anionic platinum complexes (PPN) contain similar L ligands.A number of neutral monotrichlorostannato complexes of type including have been prepared and characterized.Their δ(119Sn), δ(13C), δ(195Pt) as well as ¹J(103Rh, 119Sn), ¹J(195Pt, 119Sn), ²J(119Sn, 117Sn) and ²J(119Sn, 13C) data are given.A trans influence series, based on ¹J(195Pt, 119Sn), reveals the following sequence: H^- > PR3 > AsR3 > SnCl3^- > olefin > Cl^-.
