摘要：

The niobate, with formula KNb 6017 has a layered structure formed by stacked negative sheets and exchangeable cations in the interlayer region. In this study we discuss some structural aspects related to the ion exchange in layered hexamobate based on X-ray diffiractometry and vibrational Raman spectroscopy data. Hexamobate has two distinct interlayer regions and the potassium ions of one interlayer in particular are preferably exchanged by other cations, leading to an interstratified material.
