Structural and spectroscopic evidence for marginal metal-to-ligand charge transfer in complexes Pt(abpy)Me3X, abpy = 2,2'-azobispyridine, X = Cl, Br, I
The title complexes Pt(abpy)Me3X (X = Cl, 1a; X = Br, 1b; X = I, 1c) could be characterized by 1H NMR spectroscopy and were partially studied by x-ray diffraction (1b, 1c), cyclic voltammetry and UV-visible spectroscopy (1b). The short N=N bonds of $\sim$1.26 \AA, the occurrence of only weak charge transfer absorptions in the visible, the rather small shift of the redn. potential, and the small g anisotropy in the EPR spectrum of 1b·- indicate an only a marginal p interaction between the organometallic PtIV fragments and the excellent p acceptor abpy. on SciFinder(R)
