Structural relationships in the homologous series of alkyltriphenylstannane compounds of formula Ph3Sn(CH2)n − 1CH3, with n even and in the range 4–14 and 18

The solid state structures of several compounds in the homologous series of alkyltriphenylstannanes of general formula Ph3Sn(CH2)n − 1CH3 have been determined. For n in the range 4–10 the structures are monoclinic with space group P21/c. For n   greater than 10 they are, instead, triclinic with space group P1¯. The structural difference between the two classes is attributable to a change in the degree of control over the packing of the molecules exerted by the triphenylstannyl entity on the one hand and the alkyl chain on the other.
