Materials Data on BiC2O5 by Materials Project
C2BiO5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. C+3.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.26 Å. Bi3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Bi–O bond distances ranging from 2.08–2.51 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one C+3.50+ and one Bi3+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one C+3.50+ and one Bi3+ atom.
