The reaction of Me3SiCH2Cl2 Sn(CH2)3SnCl2Ph (6) with (tBu2SnO)3 gave a statistical mixture of the corresponding tetraorganodistannoxanes whereas the reaction of the spacer-bridged ditin tetrachlorides RCl2Sn(CH2)4SnCl2R (3, R = Me3CCH2; 4, R = Me2CHCH2; 10, R = Me3SiCH2) with the polymeric spacer-bridged ditin oxides [R(O)Sn(CH2)4-Sn(O)R]n (7, R = Me2CHCH2; 8, R = Me3CCH2; 11, R = Me3SiCH2) provided the mixed double ladder compounds {[R(Cl)Sn(CH2)4 Sn(Cl)R][R′(Cl)Sn(CH2)4Sn(Cl)R′] O2}2 (9, R = Me3CCH2, R′ = Me2CHCH2; 12, R = Me3CCH2, R′ = Me3SiCH2) in almost quantitative yield. In solution, 9 and 12 are in equilibrium with their corresponding dimers, as was evidenced by 119Sn NMR spectroscopy, molecular mass determination, and electrospray mass spectrometry. The molecular structures of 9 and 12 were established by single crystal X-ray diffraction.
