title: 4-(Cyclo-propane-carboxamido)-benzoic acid.
abstract: In the title compound, C(11)H(11)NO(3), the dihedral angle between the benzene ring and the cyclo-propane ring is 63.2 (1)°. In the crystal, mol-ecules are linked through classical cyclic carb-oxy-lic acid O-H⋯O hydrogen-bond inter-actions [graph set R(2) (2)(8)] giving centrosymmetric dimers which are extended along the b-axis direction through amide N-H⋯O hydrogen-bond inter-actions, giving one-dimensional ribbon structures. Weak C-H⋯O inter-actions are also present in the structure.
