Bi2O2CO3 crystallizes in the orthorhombic Fmm2 space group. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. Bi(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), and four equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one C(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a single-bond geometry to one C(1) and one Bi(1) atom. In the third O site, O(3) is bonded to four equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra.
Bi2O2CO3 crystallizes in the orthorhombic Fmm2 space group. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. The C(1)-O(1) bond length is 1.29 Å. Both C(1)-O(2) bond lengths are 1.29 Å. Bi(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), and four equivalent O(3) atoms. The Bi(1)-O(1) bond length is 2.58 Å. The Bi(1)-O(2) bond length is 2.64 Å. There are two shorter (2.30 Å) and two longer (2.31 Å) Bi(1)-O(3) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one C(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a single-bond geometry to one C(1) and one Bi(1) atom. In the third O site, O(3) is bonded to four equivalent Bi(1) atoms to form a mixture of corner and edge-sharing OBi4 tetrahedra.
