Abstract

Gd2TiO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to seven O2- atoms to form distorted GdO7 hexagonal pyramids that share a cornercorner with one GdO7 pentagonal bipyramid, corners with two equivalent TiO4 tetrahedra, edges with six equivalent GdO7 hexagonal pyramids, edges with two equivalent GdO7 pentagonal bipyramids, and an edgeedge with one TiO4 tetrahedra. There are a spread of Gd–O bond distances ranging from 2.29–2.58 Å. In the second Gd3+ site, Gd3+ is bonded to seven O2- atoms to form distorted GdO7 pentagonal bipyramids that share a cornercorner with one GdO7 hexagonal pyramid, corners with four equivalent TiO4 tetrahedra, edges with two equivalent GdO7 hexagonal pyramids, edges with three equivalent GdO7 pentagonal bipyramids, and an edgeedge with one TiO4 tetrahedra. There are a spread of Gd–O bond distances ranging from 2.33–2.49 Å. Ti4+ is bonded to four O2- atoms to form TiO4 tetrahedra that share corners with two equivalent GdO7 hexagonal pyramids, corners with four equivalent GdO7 pentagonal bipyramids, an edgeedge with one GdO7 hexagonal pyramid, and an edgeedge with one GdO7 pentagonal bipyramid.
