Dimethyl 5,5′-methyl­enebis(2-hy­droxy­benzoate)

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)°]. Intra­molecular phenolic O—H...O hydrogen bonds with carboxyl O-atom acceptors are present, with these groups also involved in centrosymmetric cyclic inter­molecular O—H...O hydrogen-bonding associations [graph set R₂²(4)], giving infinite chains extending across (101).
