Resumo

PLATINUM MONO-AND BIMETALLIC COMPLEXES WITH LIGANDS CONTAINING NITROGEN AND SULFUR.The synthesis of several mono-and bimetallic platinum and palladium complexes are reported.The monometallic complexes are of the type [MCl 2 (PEt 3 ) 2 L] (L=2-aminothiazol; benzothiazol; 2-imidazolidithione; M=Pt; Pd), and the bimetallic complexes ([M 2 Cl 4 (PEt 3 ) 2 L]) are derived from them.Infrared spectroscopic characterization of the monometallic complexes shows that the metal centre are coordinated through the N-endocyclic (L=2-aminothiazol; benzothiazol) and through the sulphur when L=2-imidazolidithione.Coordination of a second metal fragment occurs via the sulphur atom (L=2-aminothiazol; benzothiazol) according to infrared studies. 31P{ 1 H} NMR spectroscopy suggest that the complexes have a cis-configuration since the 1 J Pt-P are around the value found for this type of compound.
