SrUO4 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrUO4 clusters. Sr(1) is bonded in a linear geometry to one O(1) and one O(2) atom. The Sr(1)-O(1) bond length is 0.97 Å. The Sr(1)-O(2) bond length is 1.59 Å. U(1) is bonded in a linear geometry to one O(1) and one O(4) atom. The U(1)-O(1) bond length is 0.11 Å. The U(1)-O(4) bond length is 0.11 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Sr(1) and one U(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Sr(1) and one O(3) atom. The O(2)-O(3) bond length is 1.18 Å. In the third O site, O(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth O site, O(4) is bonded in a single-bond geometry to one U(1) atom.
