In the title compound, [Cd(C(8)H(4)O(4))(C(36)H(44)N(4)O(4))]·C(8)H(6)O(4), the Cd(II) atom is six-coordinated by four N atoms from the macrocyclic ligand and two O atoms from a benzene-1,3-dicarboxyl-ate ligand. The complex mol-ecules are linked by N-H⋯O hydrogen bonds, forming a one-dimensional chain structure along the b axis. The chains are further connected through N-H⋯O and O-H⋯O hydrogen bonds between the complex mol-ecule and an uncoordinated benzene-1,3-dicarboxylic acid mol-ecule, resulting in a two-dimensional supra-molecular network.
