Synthesis and properties of novel metallic compounds composed of covalent networks

在目前对新型共价网络金属化合物的合成研究中，我们成功地合成了7个新化合物。用x射线晶体结构分析成功地分析了它们的结构。LuGe_2和CaGe_3是具有新颖结构的新型超导体。碘离子填充的角钼矿I_<0.9>RhSb_12是第一个阴离子填充的角钼矿，具有半金属性质。通过电子结构计算分析了这些化合物的电子结构。

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.
