Materials Data on Bi2CO5 by Materials Project
Bi2O2CO3 crystallizes in the orthorhombic Imm2 space group. The structure is two-dimensional and consists of two Bi2O2CO3 sheets oriented in the (0, 0, 1) direction. C4+ is bonded in a trigonal planar geometry to three O2- atoms. All C–O bond lengths are 1.29 Å. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are two shorter (2.32 Å) and six longer (2.54 Å) Bi–O bond lengths. In the second Bi3+ site, Bi3+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.23 Å) and two longer (2.48 Å) Bi–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one C4+ and two equivalent Bi3+ atoms. In the third O2- site, O2- is bonded to four Bi3+ atoms to form a mixture of distorted edge and corner-sharing OBi4 tetrahedra. In the fourth O2- site, O2- is bonded to four Bi3+ atoms to form a mixture of edge and corner-sharing OBi4 tetrahedra.
