Abstract
Abstract The synthesis and 119 Sn NMR characteristics of new five-coordinate tris(trichlorostannato) 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 [M(SnCl 3 ) 3 L 2 ] where L can be CO, CN (cyclohexyl) or L 2 , a diolefin such as 1,5-COD or NBD (norbornadiene). The anionic platinum complexes (PPN)[Pt(SnCl 3 ) 3 L 2 ] contain similar L ligands. A number of neutral monotrichlorostannato complexes of type [M(SnCl 3 )L 4 ] including [Ir(SnCl 3 )(NBD)(1,5-COD)] have been prepared and characterized. Their δ( 119 Sn), δ( 13 C), δ( 195 Pt) as well as 1 J ( 103 Rh, 119 Sn), 1 J ( 195 Pt, 119 Sn), 2 J ( 119 Sn, 117 Sn) and 2 J ( 119 Sn, 13 C) data are given. A trans influence series, based on 1 J ( 195 Pt, 119 Sn), reveals the following sequence: H − > PR 3 > AsR 3 > SnCl 3 − > olefin > Cl − .
