1 H‐ and 13 C‐NMR. data are reported for the complexes [Pt (1) L] and [Pt (2) L]; 1 = OC 6 H 4 CH NCH 2 CH 2 O, 2 = OC 6 H 4 CH NC 6 H 4 O; L = PR 3 , AsR 3 , C N (cyclohexyl), DMSO, pyridine, secondary amine. The molecular structures of [Pt (2) (NHEt 2 )] (I) and [Pt (2) (PPh 3 )] (II) have been determined by X‐ray analysis. Relevant bond distances for I: Pt‐N (amine) = 2.076 Å, Pt‐N (imine) = 2.017 Å, Pt‐O = 1.992 Å and 2.002 Å; for II: Pt‐P = 2.248 Å, Pt‐N = 2.064 Å, Pt‐O = 1.964 and 2.005 Å. Both the solid and solution state data are interpreted in terms of differences in the trans influence of the ligand L. The question of metal‐ligand d‐p π back bonding to the imine is discussed.
