Materials Data on Ag9(BiO3)2 by Materials Project
Ag9(BiO3)2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are eight inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.25 Å. In the second Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.25 Å. In the third Ag1+ site, Ag1+ is bonded in a 2-coordinate geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.44 Å. In the fourth Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.09 Å. In the fifth Ag1+ site, Ag1+ is bonded in a distorted bent 150 degrees geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.49 Å. In the sixth Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. Both Ag–O bond lengths are 2.10 Å. In the seventh Ag1+ site, Ag1+ is bonded in a distorted bent 150 degrees geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.53 Å. In the eighth Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.34 Å. Bi+1.50+ is bonded in a distorted T-shaped geometry to three O2- atoms. All Bi–O bond lengths are 2.11 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Ag1+ and one Bi+1.50+ atom. In the second O2- site, O2- is bonded to three Ag1+ and one Bi+1.50+ atom to form distorted corner-sharing OAg3Bi tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to three Ag1+ and one Bi+1.50+ atom.
