BaCOO3 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 12-coordinate geometry to three equivalent O(1), three equivalent O(3), and six equivalent O(2) atoms. C(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to three equivalent Ba(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent Ba(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one C(1) atom.
BaCOO3 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 12-coordinate geometry to three equivalent O(1), three equivalent O(3), and six equivalent O(2) atoms. There is one shorter (2.88 Å) and two longer (3.23 Å) Ba(1)-O(1) bond lengths. There is one shorter (2.84 Å) and two longer (3.11 Å) Ba(1)-O(3) bond lengths. There are a spread of Ba(1)-O(2) bond distances ranging from 2.81-2.91 Å. C(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(2) atoms. The C(1)-O(1) bond length is 1.38 Å. The C(1)-O(3) bond length is 1.38 Å. Both C(1)-O(2) bond lengths are 1.38 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to three equivalent Ba(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to three equivalent Ba(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one C(1) atom.
