the preparation of C6F5AsCl2, or from subsequent reaction with elemental mercury, have been crystallographically identified as consisting primarily of secondary and tertiary substituted pentafluorophenylarsenic compounds. The crystal and molecular structures of three of these products are reported: (C6F5)2AsAs(C6F5)2 (1), (C6F5)2AsOAs(C6F5)2 (2), and (C6F5)3As (3). 1: C24F20As2, tetragonal, P21c, a 13
