195Pt-, 31P- and 15N-NMR. data are presented for 2-styrene)> (1), trans-<2(t-Bu15N=CH-CH=15N(t-Bu))> (2), trans- (3) and various complexes of the type trans-.In solution the gross structural features of 1 and 2 are shown to be in agreement with those found in the solid state; namely, 1 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 deg C in CD2Cl2.The NMR. data for 2 and 3 are compared with those of trans- (N-ligand=pyridine, 2,6-dimethylpyridine, (15N)-hexylamine, (15N)-t-butylamine and (15N)-aniline) and are discussed in terms of the donor and acceptor properties of the N-ligands.
