BaCO3 crystallizes in the orthorhombic Pnn2 space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one C(1) atom.
BaCO3 crystallizes in the orthorhombic Pnn2 space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent O(1) and six equivalent O(2) atoms. Both Ba(1)-O(1) bond lengths are 2.74 Å. There are a spread of Ba(1)-O(2) bond distances ranging from 2.73-2.93 Å. 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 1.31 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one C(1) atom.
