The material described by UC4O7 is Magnesium structured and crystallizes in the orthorhombic Pbcn space group. The structure is zero-dimensional and consists of four UC4O7 clusters. U(1) is bonded in a distorted pentagonal bipyramidal geometry to one O(1), two equivalent O(2), 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 single-bond geometry to one O(3) atom. In the second C site, C(2) is bonded in a distorted single-bond geometry to one O(4) atom. There are four inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one U(1) and one C(1) atom. In the second O site, O(4) is bonded in a distorted single-bond geometry to one U(1) and one C(2) atom. In the third O site, O(1) is bonded in a single-bond geometry to one U(1) atom. In the fourth O site, O(2) is bonded in a single-bond geometry to one U(1) atom. is represented by the CIF card [CIF]
