Materials Data on SbAsO3 by Materials Project
SbAsO3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two SbAsO3 sheets oriented in the (0, 1, 0) direction. Sb3+ is bonded in a 3-coordinate geometry to three O2- atoms. There are one shorter (2.01 Å) and two longer (2.03 Å) Sb–O bond lengths. As3+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.81 Å) and one longer (1.83 Å) As–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb3+ and one As3+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb3+ and one As3+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Sb3+ and one As3+ atom.
