The asymmetric unit of the title solvate, C(20)H(25)ClO(9)S·0.25CH(3)OH, contains one galactopyranosyl derivative and one-quarter of a methanol solvent mol-ecule. The galactopyran-ose ring is in the usual (4)C(1) conformation, and the anomeric center of the sugar has a β configuration. The value of θ (3.44°) and the range of torsion angles [or 53.1 (5)-63.0 (5)°] reflect a slight distortion of the (4)C(1) pyran-ose ring. A minor orientational disorder affects a carbonyl group, which was modeled ...[more]
