✦ Synopsis
I9'Pt-, 31Pand "N-NMR. data are presented for [PtCl, (t-Bu15N=CH-CH=15N (t-Bu)) (q2-styrene)] (l), truns-[(PtC12 (PBu3)}, (~-BU'~N=CH-C'H=I~N (2-Bu))] (2), trans-[PtCI, (~-Bu"N=CH-CH='~N (t-Bu)) (PBu,)] (3) and various complexes of the type truns-[PtCl, (N-ligand) (PBu,)]. In solution the gross structural features of 1 and 2 are shown to be in agreement with those found in the solid state; namely, I contains five-coordinate Pt and 2 is dinuclear. In 3 Pt is four-coordinate with only one N-atom of the diimine ligand being coordinated at -50" in CD,C12. The NMR. data for 2 and 3 are compared with those of truns-[PtC1,(N-ligand)(PBu3)]
(N-ligand = py ridine, 2,6-dimethylpyridine, ("N)-hexylamine, ("N)-t-butylamine and ("N)-aniline) and are discussed in terms of the donor and acceptor properties of the N-ligands.
