The structure described by Ba(C1O3)2 crystallizes in the monoclinic P2_1/c space group. Ba(1) is bonded in a 8-coordinate geometry to one O(2), one O(5), two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(3) atom. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(5) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a single-bond geometry to one O(4) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one C(1) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to one Ba(1) and one C(2) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one C(1) atom. In the fifth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ba(1) and one O(6) atom. In the sixth O site, O(5) is bonded in a distorted single-bond geometry to one Ba(1) and one C(2) atom. is represented by the CIF file [CIF]
