Materials Data on ZrTi2O by Materials Project

Abstract

Ti2ZrO crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a distorted rectangular see-saw-like geometry to two equivalent Zr and four equivalent O atoms. Both Zr–Zr bond lengths are 3.03 Å. All Zr–O bond lengths are 2.38 Å. In the second Zr site, Zr is bonded in a 12-coordinate geometry to two equivalent Zr and twelve equivalent Ti atoms. There are four shorter (3.12 Å) and eight longer (3.18 Å) Zr–Ti bond lengths. Ti is bonded in a 2-coordinate geometry to three equivalent Zr and two equivalent O atoms. Both Ti–O bond lengths are 2.09 Å. O is bonded to two equivalent Zr and four equivalent Ti atoms to form a mixture of face and corner-sharing OZr2Ti4 octahedra. The corner-sharing octahedra tilt angles range from 0–63°.
