Dimethyl 2,2'-[butane-1,4-diylbis(sul-fanediyl)]dibenzoate.

ABSTRACT: The title compound, C(20)H(22)O(4)S(2), was synthesized by the reaction of 1,4-dibromo-butene with methyl thio-salicylate. The aliphatic segment of this ligand is in an all-trans conformation. The bridging chain, -S-(CH(2))(4)-S-, is almost planar (r.m.s. deviation for all non-H atoms: 0.056 Å) and its mean plane forms dihedral angles of 16.60 (7) and 5.80 (2)° with the aromatic rings. In the crystal, the mol-ecules are linked by weak C-H⋯O inter-actions into chains with graph-set notation C(14) along [0 0 1]. The crystal studied was a racemic twin, the ratio of the twin components being 0.27 (9):0.73 (9).
