title: Dimethyl 5,5'-methyl-enebis(2-hy-droxy-benzoate).
abstract: In the title compound, C(17)H(16)O(6), 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)°]. Intra-molecular phenolic O-H⋯O hydrogen bonds with carboxyl O-atom acceptors are present, with these groups also involved in centrosymmetric cyclic inter-molecular O-H⋯O hydrogen-bonding associations [graph set R(2) (2)(4)], giving infinite chains extending across (101).
