Abstract

SILAGHI-DUMITRESCU, Luminita et al. Bromination of (AsPh₂)₂O: The Structure of Tribromo-Diphenylarsenic (V). Rev. Soc. Quím. Méx [online]. 2000, vol.44, n.2, pp.134-138. ISSN 0583-7693.

Bromination of (AsPh₂)₂O leads to cleavage of the oxo-bridge with formation of the new organoarsenic (V) bromide, AsPh₂Br₃. A crystal structure determination shows that the compound is a trigonal bipyramidal monomer with crystallographically imposed two-fold symmetry and one shorter, equatorial, and two longer, axial bromines. There are weak C-H... π and Br...Br intermolecular interactions in the solid phase.

Keywords : Bromination; tribromophenylarsenic (V); trigonal bipyramidal monomer.
