Surerconductins r>ror>erties of C8KH8 have been investisated bv AC manneticsusceptibility measurements. The measured values of T. are 1.90 K and 1.70 Kfor two samples. From the measurements under DC magnetic field, the supercon-ductivity is found to be the type II in all the field directions. H.. is markedlyanisotropic, but the angular dependence of H.. is fairly well understood by meansof the 3D anisotropic effective mass model. The characteristic parameter 7 is toolarge, e.g. 64 or 76, to apply the 2D Josephson-coupling model. So, C.KHg isregarded as a 3D superconductor with a very large anisotropy rather than a 2Done. As the obtained effective mass ratio is as large as 940 or 920, the electronicband structure of CgKHg seems more anisotropic than that of C5K. In C.KHg,superconductivity has not been found above 1.5 K.
