The material described by Y2C3O11 crystallizes in the orthorhombic Cmc2_1 space group. Y(1) is bonded in a 9-coordinate geometry to one O(4), one O(5), one O(6), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(5) atoms. There are six inequivalent O sites. In the first O site, O(4) is bonded in a distorted T-shaped geometry to two equivalent Y(1) and one C(2) atom. In the second O site, O(5) is bonded in a distorted L-shaped geometry to one Y(1) and one C(2) atom. In the third O site, O(6) is bonded in a single-bond geometry to one Y(1) atom. In the fourth O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Y(1) and one C(1) atom. In the fifth O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Y(1) and one C(1) atom. In the sixth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Y(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
