✦ Synopsis

lo3Rh, 31P and 'H NMR data are reported for the cyclometallated Rh(II1) complexes of the type RhH(Y)(C-N)L,, where Y can be either an anionic or neutral ligand, C -N is a carbon-nitrogen bidentate ligand arising from cyclometallation at the imine carbon of the Schiffs bases derived from 2-amino-3-methylpyridine and substituted benzaldehydes and L can be either PPh,, AsPh, or SbPh,. There is only a modest dependent of 6 (lo3Rh) on the nature of the benzaldehyde, a substantial change as a function of L and the most significant sensitivity, >SO0 pprn, as a function of Y. It is suggested that '03Rh NMR spectroscopy may be useful in the study of linkage isomers of SCN-. KEY WORDS '"Rh NMR 31P NMR 'H NMR Cyclometallated Rh(II1) Schiff base complexes
