Preparation of a Li+ intercalated organic derivative of the Ruddlesden–Popper phase H2CaTa2O7

The d-glucopyranose rings modified H2CaTa2O7 was further treated with 2-butanone solution of LiClO4. Li+ ion deposited on the interlayer of H2CaTa2O7, and the interlayer distance of the samples changed into 19.243(1) Å. The AC impedance measurements on the as-prepared samples exhibit improved ionic conductivity compared with original Li2CaTa2O7 sample.
