| Summary: | The crystalline selenido germanates [Li

O (
), [{Li
(thf)
}Ge
Se
] (
), and [Li
(H
O)
][MnGe
Se
] (
) (thf = THF = tetrahydrofuran) were obtained by an extraction of a glassy ternary phase of the nominal composition Li
Ge
Se
(=Li
S·2GeSe
) with water (
) or THF (
) and slow evaporation of the solvent or by being layered with MnBr
in H
O/MeOH (
), respectively. The compounds contain known selenido germanate anions, however, for the first time with Li
counterions. This is especially remarkable for the prominent
{[MnGe
Se
]
} open-framework structure, which was reported to crystallize with (NMe
)
, Cs
, Rb
, and K
counterions, but it has not yet been realized with the smallest alkali metal cation. Impedance spectroscopic studies on Li
Ge
Se
classify the glassy solid as a moderate Li
ion conductor. |
