Cd-113 MAS and static NMR study of chlorocadmate glasses
Cd-113 magic-angle spinning (MAS) and static NMR spectra were measured of fourteen kinds of chlorocadmate glasses to reveal the chlorine coordination environments around Cd2+ in the glasses in detail. The spectra of the glasses suggest that the glass structures are mainly composed of infinite double-chains of edge-shared CdCl6 octahedra, being independent of the CdCl2 content and the kinds of chlorides except for CdCl2. Cd-113 MAS and static NMR spectroscopies enabled us to reveal not only chlorine coordination number of Cd but also linkage manners between CdCl6 octahedra in the glasses.
