Abstract

Dark brown dibromine monoxide (Br₂0) has been prepared by controlled decomposition of Br0₂ and studied by infrared and UV-vis spectroscopy and bromine K-edge EXAFS. Infrared studies of Br₂0 are consistent with C_2v symmetry with V₁ and v₃ at 508 and 595 cm^-1, respectively, in the solid and at 528 and 626 cm^-1 in a nitrogen matrix. The UV-vis spectrum has an intense absorption at 47 000 cm^-1 with successively weaker shoulders at 31 200 and 22 100 cm^-1. The mass spectrum shows a parent ion (triplet) at 174/176/178 amu. Bromine K-edge EXAFS leads to the First structural characterization of a bromine oxide with d(Br-0) = 1.85 (1) Å, d(Br…Br) = 3.07 (2) Å, and Br-O-Br = 112 ± 2°.
