Here we report 1H NMR study of trans-[PtH(p-XC6H4N-N=C6H4X-p)(PPh3)2] (I) (X = Cl, F, H, and CH3). Complexes (I) were prepared in all cases by dissolving cis-[PtCl2(PPh3)2] with hydrazine hydrate in ethanol and then treating to the yellow solution with an excess of ArNH-N=NAr. The 1H NMR spectra were recorded in CDCl3 at -30°C because the complexes are rather unstable at room temperature.

Abstract
Here we report 1H NMR study of trans-[PtH(p-XC6H4N-N=C6H4X-p)(PPh3)2] (I) (X = Cl, F, H, and CH3). Complexes (I) were prepared in all cases by dissolving cis-[PtCl2(PPh3)2] with hydrazine hydrate in ethanol and then treating to the yellow solution with an excess of ArNH-N=NAr. The 1H NMR spectra were recorded in CDCl3 at -30°C because the complexes are rather unstable at room temperature.
