The reactions of <I>N</I>-picolinoyl-<I>S</I>,<I>S</I>-tetramethylenesulrilimine and <I>N</I>-trimethylammoniopicolinamidate with dichlorobis(benzonitrile)palladium(II) and dipotassium tetrachloroplatinate(II) afforded chelate complexes of formula MCl<SUB>2</SUB>[Ylide]. The structures of the complexes were examined by IR and NMR spectroscopy, and determined as mononuclear complexes with ligands coordinated through two nitrogen atoms. A reverse relationship between p<I>K</I><SUB>a</SUB> values of the ylides and C=O stretching band frequency shifts on complex formation was found, and the nature of the coordination <I>via</I> ylidic nitrogen was discussed in terms of σ- and π-character of the ligands in the chelate complexes and several related bis-ylide complexes.
