✦ Synopsis

The 13C NMR spectra of a series of Pd" complexes containing phosphine, arsine and amine ligands, have been measured. The 13C chemical shift of the carbon atom adjacent to the donor atom, and the paracarbon in corresponding phenyl derivatives can be useful probes for the determination of complex geometry. Triple resonance measurements e.g. 13C {'H, "'P} are shown to be a valuable aid in assigning '3C spectra of p hos hine p complexes. The mixed complexes trans-PdC12LL ' (L = phosphine, arsine; L ' = amine) exist as stable species in CDC13 solution and do not disproportionate to yield the symmetrical bis derivatives.
