15 N‐NMR. parameters for the complexes trans ‐[MCl 2 ( 15 NH 2 (CH 2 ) 5 CH 3 )L] are reported; M = Pt, Pd, L = PBu n 3 , PMePh 2 , P ( p ‐CH 3 C 6 H 4 ) 3 , AsBu n 3 , AsMePh 2 , As ( p ‐CH 3 C 6 H 4 ) 3 , NH 2 (CH 2 ) 5 CH 3 and (for Pt) C 2 H 4 . For both metals, the NMR. parameters depend on the trans ‐influence of the ligand L. The values 1 J ( 195 Pt, 15 N) vary from 138 to 336 Hz and can be shown to correlate with the values 1 J ( 195 Pt, 31 P) in the complexes trans ‐[PtCl 2 (PBu n 3 )L]. There is a linear relation between the 15 N chemical shifts in the complexes of the two metals. The reactions of the complexes sym‐trans ‐[M 2 Cl 4 L 2 ], M = Pd, Pt, L = a tertiary phosphine or arsine, with neutral ligands are described. 195 Pt‐, 31 P‐ and 13 C‐NMR. data are reported.
