Abstract: | A structural study was carried out on o-ClC6H4AsCl2 (I), o-BrC6H4AsBr2 (II), C6H5AsBr2 (III), and p-BrC6H4AsBr2 (IV). The normal mode frequencies and shapes were calculated and gas-phase electron diffraction was used to establish the geometric parameters of III and IV. The structure of IV was determined by x-ray diffraction structural analysis. The experimental results for I–IV (I and II were studied in previous work) were interpreted on the basis of CNDO/2 calculations for I–III.A. E.
