Materials Data on V2Cu3H6O11 by Materials Project
V2Cu3H6O11 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with six CuO6 octahedra and a cornercorner with one VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of V–O bond distances ranging from 1.70–1.81 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with four equivalent VO4 tetrahedra and edges with four equivalent CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.94–2.17 Å. In the second Cu2+ site, Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent VO4 tetrahedra and edges with four CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.94–2.52 Å. There are three 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 0.97 Å. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.61 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent V5+ atoms. In the second O2- site, O2- is bonded to three Cu2+ and one H1+ atom to form distorted corner-sharing OCu3H tetrahedra. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one V5+ and two equivalent Cu2+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and two Cu2+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and two Cu2+ atoms. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to three H1+ atoms.
