Materials Data on Cu(SbO2)2 by Materials Project

Abstract

CuSb2O4 crystallizes in the tetragonal P4_2/mbc space group. The structure is three-dimensional. Cu2+ is bonded to six O2- atoms to form edge-sharing CuO6 octahedra. There are four shorter (1.99 Å) and two longer (2.48 Å) Cu–O bond lengths. Sb3+ is bonded in a distorted T-shaped geometry to three O2- atoms. There is one shorter (1.98 Å) and two longer (2.00 Å) Sb–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cu2+ and one Sb3+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Cu2+ and two equivalent Sb3+ atoms.
