Materials Data on DyTiClO3 by Materials Project
DyTiO3Cl crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Dy3+ is bonded in a 3-coordinate geometry to four O2- and four equivalent Cl1- atoms. There are a spread of Dy–O bond distances ranging from 2.18–2.49 Å. There are a spread of Dy–Cl bond distances ranging from 2.85–3.17 Å. Ti4+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 27°. There are a spread of Ti–O bond distances ranging from 1.85–2.14 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to one Dy3+ and three equivalent Ti4+ atoms to form a mixture of distorted edge and corner-sharing ODyTi3 trigonal pyramids. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Dy3+ and two equivalent Ti4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Dy3+ and one Ti4+ atom. Cl1- is bonded in a 4-coordinate geometry to four equivalent Dy3+ atoms.
