Cd MAS and static NMR study of halogenocadmate crystals

¹¹³Cd magic-angle spinning (MAS) and static NMR spectra are measured using 23 kinds of halogenocadmate crystals with known structures to determine the isotropic chemical shifts (δ_iso), chemical shift anisotropies (Δδ), and asymmetry parameters η and then to discuss the relationship among these NMR parameters and the halide-anion co-ordination environments around Cd²⁺. The δ_iso(MAS) values of halide-anion co-ordination polyhedra of Cd²⁺ largely change with the kind of halide-anion and the halide-anion co-ordination number. The |Δδ| and η in halogenocadmate crystals is largely dependent on the structure type of crystal, but is independent of the halide-anion co-ordination number of Cd²⁺.
