Carbon-13 shielding tensors of Zeise's salt and Zeise's dimer
Abstract
The 13C cross-polarization magic angle spinning NMR spectra of crystalline Zeise's salt, K[PtCl3(η2-C2H4)], and Zeise's dimer, trans-[{PtCl2(η2-C2H4)}2], have been recorded at room temperature. The 13C chemical shift tensors have been determined. The values of the tensor elements are compared to those of the free ethylene ligand and are discussed in terms of the bonding.
