Materials Data on CuAs2H3OF13 by Materials Project
CuAs2H3OF13 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of two CuAs2H3OF13 ribbons oriented in the (1, 0, 0) direction. Cu2+ is bonded to six F1- atoms to form CuF6 octahedra that share corners with two equivalent CuF6 octahedra and corners with four AsF6 octahedra. The corner-sharing octahedra tilt angles range from 42–44°. There are a spread of Cu–F bond distances ranging from 1.88–2.38 Å. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to six F1- atoms to form AsF6 octahedra that share corners with two equivalent CuF6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of As–F bond distances ranging from 1.74–1.80 Å. In the second As5+ site, As5+ is bonded to six F1- atoms to form AsF6 octahedra that share corners with two equivalent CuF6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of As–F bond distances ranging from 1.74–1.84 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to one O2- and one F1- atom. The H–O bond length is 1.02 Å. The H–F bond length is 1.53 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. There are nine inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the second F1- site, F1- is bonded in a 2-coordinate geometry to one Cu2+ and one As5+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the fourth F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Cu2+ atoms. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one As5+ atom. In the eighth F1- site, F1- is bonded in a bent 150 degrees geometry to one As5+ and one H1+ atom. In the ninth F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Cu2+ and one As5+ atom.
