Preliminary results are described on the synthesis and characterization of novel spacer-bridged tetraorganodistannoxanes, {[[R(Cl)Sn](CH)]O} (n = 5 – 8, 10, 12; R = CHSiMe) containing particularly long organic spacers. In the solid state, these compounds reveal typical double-ladder structures with eight tin atoms per molecule, whereas in solution a partial and reversible rearrangement takes place to form tetraorganodistannoxanes, {[[R(Cl)Sn](CH)]O} (n = 5 – 8, 10, 12; R = CHSiMe), having four tin atoms per molecule.
