is obtained by reaction of 22 with silver acetate or by treatment of the organotin oxide [R(O)SnCH2]2CH2 (R=Me3SiCH2) with acetic acid. The crystal structures of 23, 24, and 28 are described and reveal that these compounds adopt double ladder structures. Depending on the identity of Z and R in chloroform solution the compounds are either dimers (n=2, 25–28) or tetramers (n=4, 22–24). Also reported are
