Materials Data on ZnH2SeO4 by Materials Project
ZnH2SeO4 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two ZnH2SeO4 sheets oriented in the (0, 1, 0) direction. Zn2+ is bonded to six O2- atoms to form corner-sharing ZnO6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are a spread of Zn–O bond distances ranging from 2.06–2.37 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.70–1.77 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Zn2+ and one Se4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Zn2+ and one Se4+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Zn2+ and one Se4+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Zn2+ and two H1+ atoms.
