Materials Data on ZnSeO5 by Materials Project

Abstract

ZnSeO5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Zn is bonded to six O atoms to form ZnO6 octahedra that share corners with two equivalent ZnO6 octahedra and corners with four equivalent SeO4 tetrahedra. The corner-sharing octahedral tilt angles are 46°. There are a spread of Zn–O bond distances ranging from 2.04–2.16 Å. Se is bonded to four O atoms to form SeO4 tetrahedra that share corners with four equivalent ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 49–58°. There is two shorter (1.68 Å) and two longer (1.69 Å) Se–O bond length. There are three inequivalent O sites. In the first O site, O is bonded in a bent 120 degrees geometry to one Zn and one Se atom. In the second O site, O is bonded in a bent 120 degrees geometry to one Zn and one Se atom. In the third O site, O is bonded in a distorted bent 120 degrees geometry to two equivalent Zn atoms.
