Materials Data on CuH2SeO5 by Materials Project
CuH2SeO5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a distorted square co-planar geometry to four O2- atoms. There is two shorter (1.95 Å) and two longer (1.99 Å) Cu–O bond length. In the second Cu2+ site, Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent SeO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.95–2.50 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 distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.68 Å) H–O bond length. Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with two equivalent CuO6 octahedra. The corner-sharing octahedra tilt angles range from 46–49°. There are a spread of Se–O bond distances ranging from 1.66–1.70 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one Se6+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one Se6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Cu2+, one H1+, and one Se6+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Cu2+ and two H1+ atoms.
