The binuclear centrosymmetric zinc complex of the title compound, [Zn-2(C7H5O3)(4)(C10H14N2O)(2)].2H(2)O, contains four benzoate ligands, two of which bridge the two Zn atoms [Zn ... Zn' 6.685 (5) Angstrom] and two of which coordinate as monodentate ligands. Each Zn atom is coordinated by three O atoms and an N atom from an N,N-diethylnicotinamide ligand with slightly distorted tetrahedral coordination geometry. The water molecules are hydrogen bonded to the nicotinamide O atoms [O O 2.756 (4) Angstrom].
