Materials Data on CuH2(SeO3)2 by Materials Project

Abstract

CuH2(SeO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cu2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.96–2.51 Å. H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.65 Å) H–O bond length. 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 1.71–1.81 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Cu2+, one H1+, and one Se4+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one Se4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Cu2+, one H1+, and one Se4+ atom.
