We have succeeded in synthesizing the new complex hydride Li 3(NH2)2I exhibiting lithium fast-ion conductivity. Structural analysis based on high-resolutionsynchrotron X-ray diffraction shows that Li3(NH3)eI has the characteristic double-layered structure with a = 7.09109(5) Å, c=11.50958(10)Å, the space group P63mc (hexagonal), and Z = 4. Because of the characteristic structure, Li3(NH2) 2I exhibits fast-ion conductivity of 1 × 10-5 S/cm at 296 K with a lithium ion transport number of almost unity, although the conductivities of the host materials Li(NH2) (3 × 10-9 S/cm) and LiI (3 × 10-8 S/cm) are very low.
