abstract
In the title compound, C17H16O6, the two methyl salicylate moieties are related by crystallographic twofold rotational symmetry with the two benzene rings close to being perpendicular [inter-ring dihedral angle = 86.6 (8)degrees]. Intramolecular phenolic O-H center dot center dot center dot O hydrogen bonds with carboxyl O-atom acceptors are present, with these groups also involved in centrosymmetric cyclic intermolecular O-H center dot center dot center dot O hydrogen-bonding associations [graph set R-2(2)(4)], giving infinite chains extending across (101).
