Materials Data on TlCuAsO4 by Materials Project
CuTlAsO4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.92 Å) and two longer (1.99 Å) Cu–O bond length. Tl1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Tl–O bond distances ranging from 2.60–3.11 Å. As5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of As–O bond distances ranging from 1.69–1.79 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Cu2+, one Tl1+, and one As5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu2+, one Tl1+, and one As5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one As5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Tl1+ and one As5+ atom.
