C NMR anisotropic chemical shielding spectra of the thiourea-ferrocene inclusion compound were measured between 125 and 294 K. The orientations and dynamic behaviour of ferrocene molecules trapped in the channels are discussed.

✦ Synopsis
The proton magnetic resonance spectrum oi the thiourea-da-ferrocene mclusion compound has been studied as a functlon of temperarurc. The five-fold zszs of the ferrocene moIeculcs are frozen III a number of non-equivalent orientations at low temperature. The onset of the reorIentatIonal motion of these axes 1s assocmted with a phase ttansnlon at 162 K.
