The material described by UBr4(NO2)2 is alpha structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one UBr4(NO2)2 cluster. U(1) is bonded in a distorted linear geometry to two equivalent O(1), two equivalent Br(1), and two equivalent Br(2) atoms. N(1) is bonded in a single-bond geometry to one O(2) and one Br(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one U(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one N(1) atom. There are two inequivalent Br sites. In the first Br site, Br(1) is bonded in an L-shaped geometry to one U(1) and one N(1) atom. In the second Br site, Br(2) is bonded in a single-bond geometry to one U(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
