The NMR parameters (1H, 13C, 31P, 195Pt) of compounds of the type cis- and trans- (M = Ni, Pd, Pt) are reported.The chemical shifts δ13C and δ195Pt (together with UV data) indicate the presence of ?-backbonding from the metal into the ?*CC orbitals.This also explaines some unusual features of the coupling constants J (13C1H), J (13C13C) and J (195Pt13C).The NMR parameters reflect an increase in the amount of ?-backbonding for Pt Pd Ni. - Keywords: Alkynyl Pt(II)-, Pd(II)-, Ni(II)-complexes, Multinuclear NMR
