Research Abstract

In the present study of synthesis of novel metallic compounds composed of covalent networks, we succeeded in the synthesis of seven new compounds. Their structures were successfully analyzed by X-ray crystal structure analyses. LuGe_2 and CaGe_3 were found to be new superconductors having interesting novel structures. An iodine-filled skutterudite I_<0.9>RhSb_12 is the first anion-filled skutterudite and shows semimetallic properties. The electronic structures of these compounds were analyzed by electronic structure calculations.
