Materials Data on K2Ti2O5 by Materials Project

Abstract

K2Ti2O5 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.73–3.21 Å. Ti4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ti–O bond distances ranging from 1.73–2.02 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one K1+ and three equivalent Ti4+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to five equivalent K1+ and one Ti4+ atom. In the third O2- site, O2- is bonded in a linear geometry to four equivalent K1+ and two equivalent Ti4+ atoms.
