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 mol­ecule. The galactopyran­ose ring is in the usual (4) C (1) conformation, and the anomeric center of the sugar has a β configuration. The value o...

description 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 mol­ecule. The galactopyran­ose 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) pyran­ose ring. A minor orientational disorder affects a carbonyl group, which was modeled with two sites for the O atom having occupancies of 0.79 (5) and 0.21 (5). The crystal studied exhibited inversion twinning.
