Abstract

SmZr4O9 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Sm3+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of Sm–O bond distances ranging from 2.33–2.68 Å. There are two inequivalent Zr+3.75+ sites. In the first Zr+3.75+ site, Zr+3.75+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing ZrO7 hexagonal pyramids. There are a spread of Zr–O bond distances ranging from 2.11–2.23 Å. In the second Zr+3.75+ site, Zr+3.75+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Zr–O bond distances ranging from 2.15–2.33 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to one Sm3+ and three Zr+3.75+ atoms to form a mixture of edge and corner-sharing OSmZr3 tetrahedra. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sm3+ and two equivalent Zr+3.75+ atoms. In the third O2- site, O2- is bonded to four Zr+3.75+ atoms to form a mixture of edge and corner-sharing OZr4 tetrahedra. In the fourth O2- site, O2- is bonded to one Sm3+ and three Zr+3.75+ atoms to form amore »« less
