New exotic superconductors with layered or cage-like structures have been developed, and characterized on their physical properties. The layer structured nitride TiNCl with a two-dimensional orthogonal network was intercalated with alkali metals as well as organic bases, which was changed into superconductors with T_<CS>=8.6-16.4K. The electron-doped β-HfNCl and β-ZrNCl with double honey-comb layered structures were swelled with organic solvent molecules, and the effect of swelling (co-intercalation) on superconductivity was studied by measuring magnetic susceptibility and NMR. New silicon clathrate superconductors have been prepared under high pressure and high-temperature conditions.

带有类似结构的新外来超导体已经开发出ED硝酸盐二维有机鲈鱼，该贝司将其变成T_ <cs> = 8.6-16.4k的CTOR通过测量磁性s灭，在高温离子下制备了溶剂和肿胀（共同相关）对超导性的影响。
