Abstract

U(O2Br)3O2BrO crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of two hydrogen peroxide molecules; one BrO cluster; and two U(O2Br)3 ribbons oriented in the (1, 1, 0) direction. In the BrO cluster, O2- is bonded in a distorted L-shaped geometry to two equivalent Br+3.50+ atoms. There are one shorter (1.73 Å) and one longer (2.39 Å) O–Br bond lengths. Br+3.50+ is bonded in a distorted L-shaped geometry to two equivalent O2- atoms. In each U(O2Br)3 ribbon, U4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of U–O bond distances ranging from 1.82–2.42 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one U4+ and one Br+3.50+ atom. The O–Br bond length is 1.87 Å. In the second O2- site, O2- is bonded in a single-bond geometry to one U4+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one U4+ and one Br+3.50+ atom. The O–Br bond length is 1.76 Å. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to onemore »« less
