A number of platinum(II) and palladium(II) complexes containing the monoanion of isatin (2,3-dihydroindole-2,3-dione, Hisat) have been synthesized by reaction of the metal halide complex with isatin, in the presence of triethylamine. The complexes have been characterised by NMR and IR spectroscopies and elemental analysis. A single-crystal X-ray diffraction study has been carried out on cis-[Pt(isat)2(PPh3)2], which shows two cis-isat ligands with their dicarbonyl functions pointing in opposite directions. Electrospray mass spectrometry was also used for characterisation; the complexes show a strong tendency to form aggregate ions with ammonium ions, and both mono- and di-cationic species are observed.
