Intercalation of triethylphosphine oxide into the interlayer space of HLaNb₂O₇·xH₂O

Abstract

Triethylphosphine oxide (TEPO) was accommodated in the interlayer space of a layered perovskite, HLaNb₂O₇·xH₂O , via a reaction with an n-decoxyl derivative of HLaNb₂O₇·xH₂O. XRD pattern of the reaction product showed that the interlayer distance of the reaction product was ca 1.8 nm. In the IR spectrum of the reaction product, no absorption bands due to n-decoxyl groups were observed, and a new absorption band (P=O stretching vibration, 1077 cm^-1) assignable to TEPO appeared.
