All products are monomeric, both in solution and in the solid state, as shown by the cryoscopically determined molar masses and crystal structure determinations, The indium-chalcogen-indium bridges are bent and exhibit angles of 112.4(1) and 116.8(2)degrees (2), 109.96(3)degrees (3), and 105.42(2)degrees (4). |
