Transport data on tin compounds with the type-I clathrate crystal structure are reported. The data illustrates why these materials are of interest for thermoelectric applications. In general, the incoherent `rattling' of the `guest' atoms in the `cages' of these open structured materials results in thermal conductivities that are atypical of simple crystalline materials, in magnitude and temperature dependence, while possessing semiconducting electronic transport properties. The results on a number of tin clathrates are presented for the first time.
