The superionic properties of the compounds RbAg 4 I 5 , KAg 4 I 5 and KCu 4 I 5 have been investigated by powder neutron di4raction and complex impedance spectroscopy. RbAg 4 I 5 and KAg 4 I 5 have room-temperature ionic conductivities of β«Ψβ¬ 0.21(6) and 0.08(5) Ψ 1 cm Ψ 1 , respectively, which inc
Raman and IR studies of a single orthorhombic crystal and of polycrystalline trigonal RbIn(MoO 4 ) 2 were performed at ambient temperature. The observed vibrational modes were assigned to the respective motions of atoms in the unit cells. It was shown that the first-order D 3d 3 β D 2h 16 phase tran
