Hydrolysis reactions of di‐ and trinuclear organotin halides yielded large novel cage compounds containing Sn−O−Sn bridges. The molecular structures of two octanuclear tetraorganodistannoxanes showing double‐ladder motifs, viz., [{Me 3 SiCH 2 (Cl)SnCH 2 YCH 2 Sn(OH)CH 2 SiMe 3 } 2 ( μ ‐O) 2 ] 2  [ 1 , Y= p ‐(Me) 2 SiC 6 H 4 ‐C 6 H 4 Si(Me) 2 ] and [{Me 3 SiCH 2 (I)SnCH 2 YCH 2 Sn(OH)CH 2 SiMe 3 } 2 ( μ ‐O) 2 ] 2  ⋅ 0.48 I 2  [ 2⋅ 0.48 I 2 , Y= p ‐(Me) 2 SiC 6 H 4 ‐C 6 H 4 Si(Me) 2 ], and the hexanuclear cage‐compound 1,3,6‐C 6 H 3 ( p ‐C 6 H 4 Si(Me) 2 CH 2 Sn(R) 2 OSn(R) 2 CH 2 Si(Me) 2 C 6 H 4 ‐ p ) 3 C 6 H 3 ‐1,3,6 ( 3 , R=CH 2 SiMe 3 ) are reported. Of these, the co‐crystal  2⋅ 0.48 I 2  exhibits the largest spacing of 16.7 Å reported to date for distannoxane‐based double ladders. DFT calculations for the hexanuclear cage and a related octanuclear congener accompany the experimental work.
