Materials Data on CuAsO3 by Materials Project

CuAsO3 crystallizes in the orthorhombic Pmma space group. The structure is two-dimensional and consists of one CuAsO3 sheet oriented in the (0, 1, 0) direction. Cu1+ is bonded in a distorted square co-planar geometry to four equivalent O2- atoms. All Cu–O bond lengths are 2.02 Å. As5+ is bonded to four O2- atoms to form corner-sharing AsO4 tetrahedra. There is two shorter (1.76 Å) and two longer (1.84 Å) As–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent As5+ atoms. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Cu1+ and one As5+ atom.

Materials Data on CuAsO3 by Materials Project

CuAsO3 is Ilmenite structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Cu1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 2.07–2.53 Å. As5+ is bonded to six O2- atoms to form edge-sharing AsO6 octahedra. There are a spread of As–O bond distances ranging from 1.89–1.92 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Cu1+ and two equivalent As5+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Cu1+ and two equivalent As5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Cu1+ and two equivalent As5+ atoms.
