Solid-state 195Pt NMR studies of the complexes Pt(en)Clx(en = 1,2-diaminoethane; x= 2, 3 or 4)
Abstract
195 Pt magic-angle spinning (MAS) NMR spectra of the monomeric complexes Pt(en)Cl2 and Pt(en)Cl4 and of the linear-chain complex [Pt(en)Cl2][Pt(en)Cl4] show that the PtII and PtIV sites in the mixed-valence complex have isotropic chemical shifts and shielding anisotropies that are surprisingly similar to those of their monomeric constituents.
