Abstract

Na4SeO5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are nine inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with five NaO6 octahedra, corners with two equivalent SeO5 trigonal bipyramids, edges with nine NaO6 octahedra, an edgeedge with one SeO5 square pyramid, and an edgeedge with one SeO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 12–33°. There are a spread of Na–O bond distances ranging from 2.34–2.80 Å.
