The title compound, [SnI3(C4H7O2)], is a member of the comparatively well known estertin family of compounds in which the carbonyl O of the 2-carbo­alkoxy­ethyl fragment bonds to Sn, augmenting its coordination and creating a five-membered chelate ring. The present case, where, as is often the case, Sn has trigonal bipyramidal coordination, is notable for the presence in the asymmetric unit of two distinct mol­ecules markedly different in terms of the trans-axial Sn-O and Sn-I distances, 2.459 (8) versus 2.631 (8) and 2.7601 (10) versus 2.7188 (9) Å, respectively, and much greater pucker of the chelate ring associated with the longer Sn-O bond.
