摘要：

Cd-113 magic angle spinning NMR, with and without H-1 cross-polarisation and decoupling, has been used to study a number of Hofmann-type clathrates and related compounds. The Cd-113 chemical shift shows a great sensitivity to the environment of Cd, even for complexes with closely related structures. The presence of five resonances due to Cd surrounded by C(x)N(4-x) (where x = 0 to 4) in Cd(CN)2 and Cd(CN)2.C6H12 indicates a static disorder of the CN groups, which makes these materials orientational glasses.
