Materials Data on Ag5BiO4 by Materials Project
Ag5BiO4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are six inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. Both Ag–O bond lengths are 2.12 Å. In the second Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.13 Å. In the third Ag1+ site, Ag1+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.20–2.62 Å. In the fourth Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.14 Å) and one longer (2.21 Å) Ag–O bond lengths. In the fifth Ag1+ site, Ag1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.19 Å. In the sixth Ag1+ site, Ag1+ is bonded in a linear geometry to two O2- atoms. There are one shorter (2.11 Å) and one longer (2.12 Å) Ag–O bond lengths. Bi3+ is bonded to five O2- atoms to form edge-sharing BiO5 square pyramids. There are a spread of Bi–O bond distances ranging from 2.20–2.45 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to three Ag1+ and one Bi3+ atom to form corner-sharing OAg3Bi tetrahedra. In the second O2- site, O2- is bonded to three Ag1+ and one Bi3+ atom to form corner-sharing OAg3Bi tetrahedra. In the third O2- site, O2- is bonded to three Ag1+ and one Bi3+ atom to form distorted corner-sharing OAg3Bi tetrahedra. In the fourth O2- site, O2- is bonded to two Ag1+ and two equivalent Bi3+ atoms to form distorted OAg2Bi2 tetrahedra that share corners with eight OAg3Bi tetrahedra and an edgeedge with one OAg2Bi2 tetrahedra.
