Materials Data on ZnSeO3 by Materials Project

ZnSeO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Zn2+ is bonded to six O2- atoms to form corner-sharing ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 50–56°. There are a spread of Zn–O bond distances ranging from 2.08–2.28 Å. Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.75 Å) and two longer (1.76 Å) Se–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Zn2+ and one Se4+ atom. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to two equivalent Zn2+ and one Se4+ atom.

Materials Data on ZnSeO3 by Materials Project

ZnSeO3 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Zn2+ is bonded to five O2- atoms to form a mixture of distorted edge and corner-sharing ZnO5 trigonal bipyramids. There are a spread of Zn–O bond distances ranging from 2.00–2.26 Å. Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.72–1.77 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Zn2+ and one Se4+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Se4+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Se4+ atom.
