Abstract

Ce3MoO7 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are three inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded to seven O2- atoms to form distorted CeO7 pentagonal bipyramids that share corners with two equivalent MoO6 octahedra, corners with three CeO7 pentagonal bipyramids, edges with two equivalent MoO6 octahedra, and edges with two equivalent CeO7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 32–44°. There are a spread of Ce–O bond distances ranging from 2.25–2.57 Å. In the second Ce3+ site, Ce3+ is bonded to seven O2- atoms to form CeO7 pentagonal bipyramids that share corners with two equivalent MoO6 octahedra, corners with three CeO7 pentagonal bipyramids, edges with two equivalent MoO6 octahedra, and edges with two equivalent CeO7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 43–46°. There are a spread of Ce–O bond distances ranging from 2.26–2.48 Å. In the third Ce3+ site, Ce3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ce–O bond distances ranging from 2.33–2.76 Å. Mo5+ is bonded to six O2- atoms to form MoO6 octahedra that share corners with two equivalent MoO6 octahedra, corners with four CeO7more »« less
