The syntheses of the new five-coordinate trichlorostannate complexes (PPN)-[M(SnCl3)2 (1,5-COD)(PR3)] (M Rh, Ir, R C6H5, p-ClC6H4, p-FC6H4, p-OCH3C6H4), (PPN)[Rh(SnCl3)2(NBD)(PR3)] and [Ir(SnCl3)(CO)(1,5-COD)(PR3)] (PPN = bis(triphenylphosphino)imine) are reported, as well as their 119Sn and 31P NMR spectroscopic characteristics. The bis-SnCl3 compounds show 2J(119Sn, 117Sn) coupling constants
