| Abstract: | The title molecule, (iodobromo)triphenylarsenic(III), As(BrI)(C6H5)3], has a dart shape, with the phenyl rings arranged in a propeller conformation I—As—C—C 61.3 (4), 43.8 (4) and 54.1 (4)°]. There is no indication that the halogen atoms have mixed site occupancies. Packing forces displace the I atom away from one phenyl ring I—As—C 117.3 (2)°] towards the other two I—As—C 109.8 (2) and 108.3 (2)°] and produce an even more pronounced leaning of the terminal bromine As—I—Br 174.78 (2)°]. |
