Materials Data on EuSbO4 by Materials Project
EuSbO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.31–2.89 Å. Sb5+ is bonded to six O2- atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedra tilt angles range from 37–46°. There are a spread of Sb–O bond distances ranging from 1.99–2.04 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Eu3+ and two equivalent Sb5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to three equivalent Eu3+ and one Sb5+ atom. In the third O2- site, O2- is bonded to three equivalent Eu3+ and one Sb5+ atom to form a mixture of distorted corner and edge-sharing OEu3Sb tetrahedra. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Eu3+ and two equivalent Sb5+ atoms.
