A new bismuth-containing layered perovskite of the Ruddlesden–Popper type, K<sub>2.5</sub>Bi<sub>2.5</sub>Ti<sub>4</sub>O<sub>13</sub>, has been prepared by solid-state synthesis. It has been shown to hydrate to form stoichiometric K<sub>2.5</sub>Bi<sub>2.5</sub>Ti<sub>4</sub>O<sub>13</sub>·H<sub>2</sub>O. Diffraction data show that the structure consists of a quadruple-stacked (<i>n</i> = 4) perovskite layer, with potassium ions occupying the rock salt layer and its next-nearest A site. The hydrated sample was shown to remove the offset between stacked perovskite layers relative to the dehydrated sample. Computational methods show that the hydrated phase consists of intact H<sub>2</sub>O molecules in a vertical “pillared” arrangement bridg...
