Abstract
The title molecule, (iodobromo)triphenylarsenic(III), [As(BrI)(C6H5)(3)], h as a dart shape, with the phenyl rings arranged in a propeller conformation [I-As-C-C 62.3 (4) 43.8 (4) and 54.1 (4)degrees]. There is no indication t hat the halogen atoms have mixed site occupancies. Packing forces displace the I atom away from one phenyl ring [I-As-C 117.3 (2)degrees] towards the other two [I-As-C 109.8 (2) and 108.3 (2)degrees] and produce an even more pronounced leaning of the terminal bromine [As-I-Br 174.78 (2)degrees].
