The title complex, [Zn-2(C7H5O2)(4)(C20H21NO4)(2)], forms dimers of the paddle-wheel cage type located at crystallographic inversion centres. The two Zn atoms [Zn...Zn = 3.0533 (4) Angstrom] are connected by four sync-sync benzoate ligands. The apical positions of the square-pyramidal zinc coordination polyhedra are occupied by the N atoms of the papaverine ligand. Upon coordination, the mutual orientation of the phenyl and isoquinoline rings in papaverine is changed compared with that in the uncoordinated ligand.
