The structure described by YC3O8 crystallizes in the orthorhombic P2_12_12_1 space group. Y(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(6), one O(7), and one O(8) atom. There are three 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(7) atom. In the second C site, C(2) is bonded in a linear geometry to one O(3) and one O(4) atom. In the third C site, C(3) is bonded in a trigonal planar geometry to one O(5), one O(6), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(5) is bonded in a single-bond geometry to one C(3) atom. In the second O site, O(6) is bonded in a linear geometry to one Y(1) and one C(3) atom. In the third O site, O(7) is bonded in an L-shaped geometry to one Y(1) and one C(1) atom. In the fourth O site, O(8) is bonded in a distorted bent 150 degrees geometry to one Y(1) and one C(3) atom. In the fifth O site, O(1) is bonded in an L-shaped geometry to one Y(1) and one C(1) atom. In the sixth O site, O(2) is bonded in a bent 150 degrees geometry to one Y(1) and one C(1) atom. In the seventh O site, O(3) is bonded in a distorted single-bond geometry to one Y(1) and one C(2) atom. In the eighth O site, O(4) is bonded in a distorted single-bond geometry to one Y(1) and one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
