N-Benzylacetimidic acid ethyl ester (L) yields a stable complex of the type trans-[PdCl2L2] with the nitrogen atoms as s donors. This is not readily convertible to an ortho-palladated complex. An X-ray crystallographic study reveals a centrosymmetric structure [monoclinic, space group P21/c, a = 9.983(4), b = 9.492(23), c = 14.111(10) Å, ß = 114.02(4)°, and Z = 2]. Splitting of the 1H n.m.r. signal corresponding to the CH3C=group is attributed to the presence of two slowly interconverting rotamers (probably about the Pd-N bond), while a more rapid fluxional mode must be responsible for the temperature variation in the chemical shift of the CH2O groups.
