New alpha,omega -bis(trichlorostannyl)alkanes, Cl3Sn(CH2)(n)SnCl3 [n = 3-5, 8], have been synthesized via tin-phenyl bond cleavage reactions on alpha,omega -bis(triphenylstannyl)alkanes, Ph3Sn(CH2)(n)SnPh3 [n = 3-5, 8], using either SnCl4 or concentrated hydrochloric acid. Some key missing links, (H2O)Cl3Sn(CH2)(3)SnCl3(H2O) (1a) and (H2O)(2)Cl3Sn(CH2)(3)SnCl3(H2O)(2) (6), in the hydrolysis pathway of organotin trichlorides were identified. Crystal structures of the nonassociated di-tin compounds (H2O)Cl3Sn(CH2)(3)SnCl3(H2O) (1a) and (H2O)(2)Cl3Sn(CH2)(3)SnCl3(H2O)(2) (6, isolated as the 18-crown-6 cocrystal acetonitrile solvate) as well as the polymeric hydrolysis product [H2O(OH)Cl2Sn(CH2)(3)SnCl2(OH)H2O . 2H(2)O](n) (7 . 2H(2)O) are reported.

mass spectrometry. For the latter the essential doubleladder motif is maintained for all n in the solid state, but subtle changes in alignment of the ladder planes occur. Separation between the two layers of the doubleladder ranges from approx. 8.7 Å (for 25, n=5) to approx. 15 Å (for 30, n=12). In solution there is some dissociation of the doubleladders into the corresponding dimers. The degree of
