Materials Data on ZnCu(SeO3)2 by Materials Project
CuZn(SeO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with six equivalent ZnO6 octahedra. The corner-sharing octahedra tilt angles range from 50–57°. There are a spread of Cu–O bond distances ranging from 1.99–2.44 Å. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six equivalent CuO6 octahedra. The corner-sharing octahedra tilt angles range from 50–57°. There are a spread of Zn–O bond distances ranging from 1.99–2.41 Å. Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.74 Å) and two longer (1.76 Å) Se–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cu2+, one Zn2+, and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cu2+, one Zn2+, and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cu2+, one Zn2+, and one Se4+ atom.
