In the title complex, [Zn(C₇H₆NO₂)₂(C₁₀H₈N₂)], the Zn^II cation is coordinated by two aminobenzoate anions and one 2,2'-bipyridine ligand in a distorted trigonal-bipyramidal geometry. The carboxylate group of one aminobenzoate anion coordinates to the Zn^II cation in a monodentate manner, whereas the carboxylate group of the other aminobenzoate anion chelates the Zn cation with different Zn-O bond lengths. Intermolecular N-HN and N-HO hydrogen bonding is present in the crystal structure.
